Ashley Tisdale’s wild “Bikini” beach party in Malibu

Ashley Tisdale has a lot to celebrate and what better way to do it than hold a wild beach party, invite some famous friends and your gorgeous boyfriend.

She's got a hot career as an actress and producer and has reconciled with hunky music director Scott Speer. To top it off, she looks unfairly fabulous in a lime green stripper bikini.

Plus, she's still three years away from 30.

'Birthday party at the beach:)' the 27-year-old tweeted today as she partied with girlfriends and Speer at a private residence in Malibu.

One of the friends was Selena Gomez, with the other half of popstar Justin Bieber initially hiding her face behind Ashley's dog, Maui, on arrival - before frolicking in the sea with a male companion.

For the party, the High School Musical star wore a lime green bikini with dangling tassels.

Clearly, the daily workouts at the gym have paid off. Her body was perfectly toned and tight.

The party house had it's own beach front and The Hellcats actress and her friends took full advantage of it.

For a bit of modesty, the singer slipped on a pair of short denim trousers.

Ashley and Scott, who wore jeans and a long-sleeved shirt the entire time, then enjoyed a make out session on the shore.The duo had split in December but are now stronger than ever.

Just gorgeous! Ashley looked thrilled that pal Vanessa Hudgens could make it

The former Ford model will play a high priced escort on the fifth season of the FX biker show, Sons of Anarchy.

While on-set last week, Ashley tweeted her excitement prior to hopping in front of the cameras, writing, 'Doing 2 episodes! So excited because it's my favourite show!'

It's hardly the only thing she's up to. The Weinstein Company announced she will be one of the stars in the much anticipated Scary Movie 5.

She's also the co-executive producer on the Bravo show Miss Advised, for which she gives dating advice on a regular basis.
