'Jenny From the Block' hitmaker J. Lo held her 46th birthday party at 1 Oak Southampton night club on Saturday (25 July).
The-mother-of-two, who actually turned 46 on Friday, showed off even more skin than ever while flaunting her cleavage and derrière in the frock.
As the birthday girl, Jennifer made sure she was the centre of attention in the daring black cut-out dress with the sheer panels leaving very little to the imagination.
Flaunting her tousled shorter locks, Jennifer looked fierce as she posed for some photos before partying up a storm inside.
French Montana, Natasha Bedingfield and Olivia Culpo were among the famous faces celebrating her birthday. Who knew they were all friends?
But there was another familiar face, her on-again beau Casper Smart.
Jennifer posed up a storm with Casper at the party, with one image showing the pair in front of a gold-coloured curtain, with Jennifer placing her hand on his chest.
Partying aside, Jennifer has spent the last month filming on new NBC show, Shades of Blue. Jennifer plays a single mother, who is working undercover for the FBI's anti-corruption force, but faces the dilemma of her own family's welfare and that of her police family.
