Katie Cassidy has emerged as one of the front-runners to play the lead role in the movie adaption of the bestselling book “Fifty Shades of Grey,” The Daily Mail reported. Cassidy, 25, who has starred in “Gossip Girl” and “Melrose Place,” is believed to be in competition with Emma Watson, Emma Stone and “Pretty Little Liars” actress Lucy Hale to play the role of Anastasia Steele in the erotic love story, according to sources.

Meanwhile, rumors about who will take on the role of Christian Grey are also flying. Names on the list include Ryan Gosling, Zac Efron, Alex Pettyfer and Ian Somerhalder of “The Vampire Diaries.”

“Magic Mike” star Channing Tatum was recently linked to the part, but said in a recent interview that he would only take on the part if his wife, Jenna Dewan, could play Anastasia.

“I’d only be allowed if my wife was Ana,” he said. “She’s read the books so I don’t think she’d be impressed if she couldn’t be Ana.” [Source]

Longtime pals Zac Efron and Rumer Willis are taking their relationship to the next level, an insider tells Star. They celebrated their new status with a romantic Turks & Caicos getaway in late December.

“Zac had been trying to win back Vanessa Hudgens, but she’s moved on with Austin Butler,” as Star revealed.

Zac, 24, finally realized that the right woman had been there for him all along. “At first, they’d socialize in groups, then Rumer started going over to Zac’s L.A. house,” says the insider. “She’d decorate and make the place really home — then she began spending the night, and they’re acting like a couple. Zac told Rumer he’s developing strong feelings for her.”

The insider adds that he’s already in good with her folks, Bruce Willis and Demi Moore! [Source]

Are Zac Efron and Rumor Willis dating? It’s possible! The two, who claim to be just friends, have been spotted out on the town again.

Zac Efron and Rumor Willis look adorable together, and they obviously get along. Efron is one of Hollywood’s hottest young leading men, and Willis can’t be immune to his smoking hot good looks.

Zac hasn’t seriously dated anyone since breaking up with longtime girlfriend, Vanessa Hudgens, in late 2010, but has been linked to Theresa Palmer and Emma Roberts.

It is definitely time for Efron to get back in the dating game, and Willis is a perfect match for him. Although Rumor is much different than Vanessa, that may be just what Zac needs right now.

Hudgens has moved on with Disney star, Austin Butler, and it’s time for Efron to do the same. Rumor is fun and frisky, and the pair could easily become one of the hottest young celebrity couples. [Source]

Zac Efron is reportedly dating Emma Roberts. According to a new report, the pair where seen “full-on making out” at an after-hours party hosted by Lance Bass on October 30.

“Zac and Emma both wound up at Lance’s party, and before the night was over, they were all over each other,” a source said. “They took each other’s numbers and seemed into each other.”

Efron has previously dated his “High School Musical” costar Vanessa Hudgens, while Roberts — the niece of actress Julia Roberts — has been linked to “Glee” star Chord Overstreet. [Source]

Zac Efron might have recently been spotted frolicking on the beach with former “High School Musical” co-star Ashley Tisdale, but according to InTouch Weekly the young leading man only has eyes for Rumer Willis. The mag reports that Zac has even had a meeting with Rumer’s mom, Demi Moore, where the 23-year-old brought her flowers. Photos of the pair have yet to surface and a rep for Zac was not immediately available for comment when contacted by Access Hollywood. [Source]

Following the report saying that Vanessa Hudgens’ ex-boyfriend, Zac Efron, was dating a Victoria’s Secret model, another rumor has been emerged, insisting that Zac was not dating the model. Previously, the “High School Musical” star was spotted booking a VIP section of Roxbury club in Hollywood to date a mystery lady last March. The particular lady was later reported to be an underwear model named Candice Swanepoel.

The spinning rumor said that Zac was getting really close to the underwear model during a date night at the luxurious club. A witness said that Zac and Candice shared a romantic dance in a VIP room and the actor asked the light to be deemed. Not only that, the “Hairspray” actor was reportedly going home together with his mystery date.

In contrary to the swirling gossip, a source has leaked information about Zac’s rumored new girlfriend, insisted that the mystery blond Zac has dated with was not Candice. The source said, “He wasn’t at the club with her. He was with Laura New. She’s a friend of Zac’s and Vanessa [Hudgens]‘s.” In addition, Laura is a lead singer of a pop band, The Beach Girl5.

That was the first time Zac was reportedly dating a girl after breaking up with Vanessa. In the other hand, Vanessa has already introduced a new boyfriend. She was snapped spending time with Josh Hutcherson at Coachella Music and Art festival last weekend. Interestingly, the couple was hanging out at the gig together with Laura New.

While his ex-girlfriend had fun with her new lover at the annual festival, Zac chose not to attend the same event. He decided to have fun at another occasion as he was spotted hanging out with some unknown ladies at the Plan B concert at El Rey theater in Los Angeles on Tuesday, April 19. [Source]

In late March, Zac Efron caused tongues to wag when he was spotted at cozying up with an unidentified blond at a Hollywood nightclub. Who was that mystery woman? None other than Victoria Secret model Candice Swanepoel.

“She met Zac for the first time at the Roxbury that night,” a source close to the uber-thin lingerie model told Allie Is Wired.

According to the source, who claims to be a friend of Swanpoel’s, the two were introduced by a mutual friend. While other sources have said there was no PDA between the two, this one claims there were some very public displays by the end of the night.

Swanepoel made headlines just a few days later when photos from a Victoria’s Secret swimwear shoot in L.A. revealed the South African beauty had lost a startling amount of weight. [Source]

Although he has been linked to other Hollywood beauties ever since he is back to the single market, Zac Efron allegedly isn’t ready to let Vanessa Hudgens go just yet. In fact, it has been claimed that the “Charlie St. Cloud” star is desperately trying to win the heart of his ex-girlfriend back.

One source told Us Weekly, “Zac is desperate to win [Vanessa] back. That’s why they’ve been together recently – he’ll do anything.” Previous report gave the impression that Zac was the one who ended the four-year romance, but insiders insisted that he is left heartbroken by the break-up. The source added, “He loves her.”

Report of Zac and Vanessa having taken a decision to end their romance surfaced in mid-December. One friend told E! Online at the time, “It’s nothing dramatic. There’s no third party involved.” Another one chimed in to say, “They are still talking and still friends. There’s no drama. No one cheated. They just grew up.”

Weeks later, speculation of them getting back together ran high. 23-year-old Zac was spotted visiting Vanessa after she returned from her chiropractic appointment on January 4. A few days later on January 7, the two were seen acting flirty with each other during a night out in Los Angeles. One eyewitness told E! the former couple were “dirty dancing and making out” at the Eden nightclub. [Source]

He’s one of the hottest studs in Hollywood, and rumor has it that Zac Efron has taken a liking to actress Rumer Willis. According to a report, the “High School Musical” hunk and the “House Bunny” babe were recently spotted flirting up a storm while on vacation at Parrot Island. Of course, Mr. Efron’s camp will only say that Zac and Rumer are “just friends,” and since nothing is confirmed, this is still very much mere speculation.

Although the fact that Zac recently split with his longtime love Vanessa Hudgens while Miss Willis also parted ways with Micah Alberti does bring up some serious questions. [Source]

Since our talented colleagues broke the news last week that Zac Efron and Vanessa Hudgens had called it quits, we have learned that Kellan Lutz isn’t the only person Zac has been palling around with in New Orleans. A production source tell E! News that Efron, 23, has grown “chummy” with his “The Lucky One” costar Taylor Schilling.

Remember, sources insist there was no third party involved in Zanessa’s split, and they are sticking to it. What we’re hearing is that Zac has been leaning on good friend Taylor, 26, during this hard time.

“They joke around, eat together sometimes, run lines,” says our insider, who insists, however, that the relaysh has not yet turned romantic. Or, as the source puts it, “Nothing out of the ordinary.”

Everything above certainly is not out of the ordinary for costars, but just sayin’ we’ve seen where this “good friends” path has led many before. As for how Efron is spending his nights? Seems Zac is mingling with “the Twilight guys” and has become good buds with Kellan’s crew.

“They are a rowdy bunch, and I think that’s influenced him to want to be free,” adds our on set insider. [Source]
