Coming in support of her boyfriend, J.Lo stole the attention with her skin-baring and glam-up look. The 52-year-old actress/singer bared her cleavage in a white Georges Hobeika gown with a plunging neckline trimmed in crystals, which she paired with matching silver platforms and a sparkly clutch.

Ben, meanwhile, looked dapper in a classic black tuxedo with a white shirt and a black bow-tie. He completed the formalwear with shiny black leather shoes while sporting well-trimmed and thin facial hair.

Earlier on Friday, Jen also accompanied Ben at a "The Last Duel" photo call. For the promotional event, the duo opted for more casual look with the "Hustlers" star donning a two-piece outfit and high heels. Her hair was styled in high ponytail and she carried a black bag.

They moved on with different persons but after several failed relationships, they rekindled their romance in April. It has been reported that the pair have been house hunting in Los Angeles, apparently looking to buy something together, but they haven't made their decision just yet.
