They are the squeaky clean stars of wholesome Disney dramas.
But today it seemed Vanessa Hudgens and Selena Gomez were prepared to flirt with their wild side as they attended Ashley Tisdale's birthday celebrations at a beach house in Malibu.
Justin Bieber's squeeze, who is currently making the shift from Wizards of Waverly Place innocence to Spring Breakers debauchery, was seen frolicking on the sands with a male companion.

Her friend heaved her onto his shoulder to give her a fireman's lift into the sea.
But the pretty 19-year-old clearly didn't want to soak her locks prior to the evening's festivities, and quickly scarpered back out of the water.
Meanwhile, Vanessa and beau Austin Butler - who both starred alongside Ashley in the all-singing, all-dancing High School Musical extravaganza and spin-off - looked prepared with an overnight bag.

The former squeeze of Zac Efron, 23, showed off her trim midriff and belly piercing in animal print trousers together with a delicate cream cropped lace top.
Austin was dutifully on carrying duty, juggling two bags and his phone as his girlfriend followed.
Birthday girl Ashley Tisdale, meanwhile, was seen in smooching boyfriend Scott Speer.
She was dressed appropriately for the weather in a lime green string bikini and Daisy Dukes.
Ashley and Scott, who wore jeans and a long-sleeved shirt the entire time, enjoyed a make out in full view over onlookers, cementing they are stronger than ever after their split in December.
