Zac Efron joins Seth Rogen for first R-rated film‎

Zac Efron made his name playing a singing high school heartthrob, but as his newly announced film indicates, the "High School Musical" star has clearly graduated.

Deadline reports that Efron has signed on to play a hard-partying college student in an R-rated comedy, starring opposite Seth Rogen, whose character lives nearby Efron's frat house and has his life turned upside down as a result. It's standard fair for the delightfully filthy mouthed Rogen, and a huge step in a new direction for Efron.

Since finishing his Disney days, Efron has worked to establish a new, more mature identity. He danced with adults in "Hairspray," and then there was the well reviewed indie period piece, "Me and Orson Welles," in 2008, and while the 2009 comedy "17 Again" cast him back in high school, he was able to perform in a different context, with more adult themes sprinkled throughout, and its relative success -- the film grossed $136 million worldwide -- helped launch a varied next two years.

Should Zac Efron Have Stopped Ryan Rottman From Driving Drunk? ‎

Zac Efron, Rumer Willis, Ryan Rottman and frieds attended Dillon's Irish Pub in Hollywood and ordered a total of 7 Kamikaze shots, 8 or 9 mixed drinks and 3 - 4 beers, reports TMZ. Zac and Ryan both left at 9:30 separately.

By 9:45, Ryan was in police custody & apparently was 'hammered'. When Zac's rep was asked if the actor urged his friend to take a taxi they did not repond. WHO'S FAULT WAS IT?!

Ashley Tisdale and Zac Efron: Are They Officialy Committed? ‎

Ashley Tisdale and Zac Efron were caught making nice in some sexy photos snapped at Tisdale 26th birthday celebration this weekend, and the gossip world is still talking. The photos naturally led to some speculation concerning the pair, especially in light of the fact that Zac Efron's ex is none other than Tisdale's best friend, Vanessa Hudgens. Could Tisdale betray her best friend like that? And even if there is anything non-platonic between Ashley and Zac, is the sheer fact that Efron showed up a slap in the face to Hudgens?

Well, the rumors of a cold-hearted hook-up are completely false. And to be fair, Tisdale and Efron both knew each other from "High School Musical", where Hudgens met Efron, as well. Clearly elated about Zac's presence, Tisdale happily tweeted, "So happy zacary made it to my party!!! He's my brother/best friend!!!" Efron's appearance sounded like more of a surprise than well-plotted back stab, and a close friend of Tisdale's and Efron's has confirmed this.

The birthday party took place on the beaches of Malibu over the weekend, with the birthday celebration being topped off when Efron arrived and gave her a piggyback ride down to the water and then back up to the beach abode. Efron was also seen giving Tisdale a loving peck on the cheek, E! Online reported yesterday.

Miss Tisdale thanked her many fans on Twitter for their well-wishes on her special day, as she wrote, "Thanks to all the fans for ur amazing birthday wishes!!! U r the best! I love you! I am so grateful 4 u all."
