Vanessa Hudgens celebrated her 22nd birthday at Pure Nightclub in Las Vegas with her close girl pals.

The High School Musical star and friends Ashley Tisdale and Brittany Snow partied inside the VIP area of the Nightclub at Caesar’s Palace. The actress was seen to be having a good time and did not show any after-effects of her break-up with long time boyfriend Zac Efron, according to reports.

“They’re my best friends,” Hudgens told ”I got to have my girlfriends around.”

Last week, as reported, she and Zac Efron ended their four-year relationship. The break-up was amicable and their rep gave a statement saying that there was no third party involved.

Zac Efron on his part has moved on with his life. If latest reports are to be believed then he is dating his co-star in the movie 'The Lucky One' actress Taylor Schilling.

It was recently reported that Zac and Hudgens had split.

It seems he advised Zac to move on from his High School musical image if he wanted to be taken seriously. Zac took it a step further and broke off with Hudgens as he felt the relationship was not going anywhere and the two were stuck with the image of high-school sweethearts.
