Jennifer Lopez celebrates her 45th birthday in two days, but if you've scrolled through her Instagram account you're probably convinced that she's positively ageless. Yesterday, the singer and American Idol judge, who has spent the past week enjoying some time off and relaxing poolside with BFF Leah Remini, posted a picture that shows off her killer physique and washboard abs (above).

In the photo, J.Lo wears a brown bikini paired with a fedora, aviator sunglasses, and large hoop earrings. "She yelled at me 'DONT MOVE!' Another shot by Remini ... #shemakesmelaugh #notmad #loca #loveher #shesgettinggoodatthis," Lopez captioned the picture. The two, who have been enjoying a summer vacation in the Hamptons, clearly enjoy each other's company. On Friday, Lopez shared a video Remini took of her that features the former King of Queens actress poking fun at her friend's glamorous poolside style. Can we get in on that pool party?
