The former costars and BFFs took to Instagram to celebrate the annual holiday, rocking colorful bikinis and saluting the camera as they posed for pics at Tisdale's barbecue.
"God bless the freedom warriors that have fought for our country. Happy Memorial Day," the Spring Breakers star captioned the sexy shot, looking flawless in her Mara Hoffman bikini and cover-up.
"BBQ at my house celebrating #memorialday," Ashley wrote, posting the same pic on her Instagram (with a different filter, natch).
Tisdale—who came in at lucky No. 7 on Maxim's hot 100 list—recently told E! News how she maintains her fab figure, "I keep up with eating pretty healthy during the week, and I always have my cheat weekends," she said. "I always take time to work out and at least do a little cardio and weights every day."
Ash's equally fit bestie also hosted L.A.'s first-ever 5K neon run over the weekend, where she sported a pink wig and polar bear hat for the occasion.
Keep up the good work, ladies! You both look great.
