Courteney Cox [1] celebrated her 55th birthday [2] on June 15, but you would never guess it just by looking at her latest Instagram post [3]. On Sunday, the actress blessed our feed with a video of herself enjoying a relaxing pool day, and wow, Courteney looks incredible! Clad in a black bikini, Courteney showed off her toned figure as she stepped out of a pool and sipped on a refreshing drink. "Oh so now I finally get what @missymisdemeanourelliott meant by put your thing down, flip it, and reverse it . . . only took me ten years," she captioned it, referencing Missy Elliott's "Work It," which plays in the background. Of course, we weren't the only ones in awe of Courteney's killer bod. Pals Kaley Cuoco, Jennifer Meyer, Busy Philipps, and Isla Fisher [4] all commented with messages of support. "My god you look good!!!!!!! 💗❤️" Jennifer wrote.

Courteney's sexy bikini post comes a month after her fun-filled birthday trip in Cabo with BFF Jennifer Aniston [5]. The pals were joined by actresses Mary McCormack, Kristin Hahn, and Amanda Anka and appeared to have a blast as they soaked up the sun. Shortly after their getaway, Courteney and Jennifer reunited with their former Friends costar [6] Lisa Kudrow, proving they're still the queens of girls' night.
