Jennifer, 44, looked simply stunning in the photo, which was taken by her friend, The King of Queen star Leah Remini.
Mum-of-two Jennifer shared the snap via Twitter on Saturday (19 July) as she took a break from her American Idol judging duties and recent promo of her brand new album, A.K.A.
The actress and singer was captured looking out into the distance with water glistening on her chest after taking a dip in the pool.
J.Lo sure knows how to work the poolside glam look!
Jennifer wrote on Twitter: "My friend took this pic and made me post it! Guess who? @LeahRemini #vacation #summertime #backtoworksoon."
Last week (17 July), Jennifer went au naturel as she posed for a make-up free photo, while being photobombed by her son Max. It seems the 'Jenny From The Block' singer is quite a fan of the selfie, as she sent Twitter into overdrive earlier this month when she cosied up to Michelle Obama!
