While her BFF Vanessa Hudgens is busy filming Spring Breakers down in Miami, Ashley Tisdale is having some fun in the sun on her own.
In a pic posted to her Instagram Thursday, the Hellcats star showed off her trim body and toned tush (with tan lines) in a skimpy brightly colored string bikini.

"What a beautiful day," the 26-year-old wrote along with the photo.
In February, Tisdale made her red carpet debut with her beau of two months, Boys Like Girls lead singer Martin Johnson.
