Zac Efron and Vanessa Hudgens Break Up

Sad, but true - Zac Efron and Vanessa Hudgens have officially called off their relationship. After four years of being together, the High School Musical stars have felt it is time to move on. When asked about Efron, Hudgens said, "we're good" even though Zac said he felt the relationship was going nowhere.

Feeling the need to get away and celebrate, Hudgens flew off to Las Vegas to party with her best friends Ashley Tisdale and Brittany Snow. With her birthday just nine days ago (December 14th) she told USMagazine.com, "they're my best friends...I got to have my girlfriends around!"

But, 2011 is going to be a breakout year for Vanessa with three new movies just around the corner. With 'Sucker Punch', 'Beastly' and 'Journey 2: The Mysterious Island' she has a ton of work on her plate.

Meanwhile, it has been rumored that Zac Efron is dating Taylor Schilling who starred with him in 'The Lucky One'.

Whatever happens it is hard to see the stars grow up and move on while we all wish High School Musical 4 would come true.

Sharpay Evans Gets Her Own Spinoff Instead of High School Musical 4

Thought that Sharpay Evans was history? Think again! Ashley Tisdale (阿什丽·提斯代尔) is back in her role! Disney has announced an all-new Disney Channel Original Movie, Sharpay's Fabulous Adventure!

The proposed plot is that Sharpay is discovered by a talent scout and heads for Broadway hoping to be discovered and make it to the big time. But, the competition is much tougher than she planned.

Sharpay's Fabulous Adventure is scheduled to start filming this summer and premiere on Disney Channel next year. No word yet if Zac Efron, Vanessa Hudgens, or any of the rest of the High School Musical cast will make an appearance.
