Partytime! Jennifer Lopez couldn’t resist making a quick outfit change as she headed to the Balmain afterparty in New York on Monday night with her boyfriend Alex Rodriguez

Jennifer opted to shun the cardinal legs-or-cleavage rule in favour of full on glamour as she flashed a peek of her cleavage in the thigh-skimming dress, which was adorned with thousands of blue and red beads.

She shrugged a black feather coat from designer Alice McCall over her shoulders and complemented the look with red pom pom heels.

Having worn her long blonde tresses down for the red carpet, the Love Don’t Cost A Thing hitmaker decided to wear her hair – which was colored to a perfect honey blonde shade ahead of the event by colorist Adrian Wallace at New York salon Rita Hazan – up in a high bun and switched her nude pink lipstick for a bold red lip.
