PHOTOS: Ashley Tisdale Shows off Bikini Body In Birthday Snaps

The High School Musical star made the most of her Instagram account...

Ashley Tisdale celebrated her birthday in serious style yesterday night, gathering up all of her impossibly hot friends for a bonfire on the beach.

And, looking at that amazing bikini bod, it's easy to forget that the 'High School Musical' star is 27 years old now, isn't it?

Ashley made sure she kept her followers updated on all the birthday fun, posting snaps of her and her pals to Instagram throughout the night.

The gorgeous blonde donned a teeny-weeny fringed yellow bikini (and even teenier denim shorts!) to begin with but, as the night went on, swapped the summer festival gear for something a little warmer.

Like, say, a roaring bonfire and a stick full of marshmallows.

The starlet had an awesome night, judging from her snaps, and kept a big grin on her face throughout the evening; we wonder if that has anything to do with the pink Vespa she was gifted from the folks at Op.

Jealous? Us?

Maybe just a little bit...


That fringed yellow bikini is so perfect for the summer festival fashion packs! And, of course, perfect for showing off Ashley Tisdale's rockin' great abs...
