Vanessa Hudgens is livin’ it up!

The former “High School Musical” star who reportedly recently split from her longtime love, Zac Efron, celebrated her 22nd birthday with girlfriends in Las Vegas over the weekend.

The brunette beauty kicked off the fun-filled evening on Saturday with a dinner at Social House alongside five of her close friends, including former “HSM” co-star and current “Hellcats” star Ashley Tisdale, and actress Brittany Snow.

The gorgeous group then made their way to Caesars Palace, where Vanessa hit the red carpet at PURE nightclub — looking stunning and sexy in a silver mini-dress — to greet fans and pose for photos.

As for how she and Zac are handling their breakup, Vanessa assured the crowd that the two “High School Musical” stars are still speaking, telling the press, “We’re good,” before flashing a quick thumbs up.

Once inside, the adorable actress danced the night away, before heading back to the now-famous Emperors Suite (where the boys of “Hangover” stayed in 2009’s hilarious hit film) with her friends shortly after 1 AM.

As previously reported on AccessHollywood.com, after four years together, Vanessa and Zac, who played on-screen couple Troy and Gabriella in the hugely successful “High School Musical” series of films, reportedly recently split.

“It’s nothing dramatic,” a source told E! Online’s Marc Malkin, who broke news of the split. “There’s no third party involved.”

Apparently there was no drama in the break-up, another source told Malkin.

“They were together for so long. It just ran its course,” the source said.

While their romance may be over, Zac and Vanessa remain close.

“They are 100 percent still good friends,” a source told People.

Reps for Zac and Vanessa did not respond to a previous request for comment from Access Hollywood.
