Although presenter Zac Efron attended the Oscars solo, the “High School Musical” hottie is not on the market, ladies.

“I’m meeting up with Vanessa [Hudgens] at Vanity Fair,” he explained to me of her absence during the Governors Ball.

When I asked if the twosome would be attending E!’s own Oscar afterparty at Drai’s, Zac admitted he didn’t know what their party plans were post-VF because his lady is in charge of that…

“I leave all the planning up to her,” he said. “She RSVPed to all the parties for us.”

While attending the star-studded soiree, Zac couldn’t wait to rub elbows with “Hurt Locker” star Jeremy Renner. He was quick to congratulate Jeremy, as well as producer Greg Shapiro, who was proudly clutching his statue. [Source]
