Ashley's Bikini Vacation

Miss Tisdale surfs and soaks up the sun. 7 Photos »

Besties Ashley Tisdale and Haylie Duff took advantage of LA’s sunshine on Tuesday morning and went for a hike at popular hotspot Runyon Canyon.

Despite the main focus of their outing being exercise, both ladies were looking cute as they broke a sweat. Ashley, 25, was wearing red sunglasses and some teeny short while Haylie opted for a little more cover up with a cute cut off sweatshirt.

On Monday, Ashley celebrated the birthday of some one very special in her life.

Her insanely adorable puppy Maui! Ashley tweeted:

“its Maui’s birthday today!! i got her some yummy dog treats for the special occasion. I will share some pics tonight!”

We love a good dog birthday celebration.
