The 'On The Floor' singer and her boyfriend were caught by surprise by the mystery man.
Jennifer Lopez and Casper Smart fell victim to a photobomber this week as they headed out on a shopping trip to Beverly Hills.
The couple were walking hand-in-hand down the street when a mystery man popped up behind to give a wave.
After a few seconds, the pair apparently noticed what was going on and found the funny side.
J-Lo had her toned legs on show in a short grey shirt-dress with Casper keeping things casual in a white t-shirt and jeans shorts.

Meanwhile, the singer has been busy filming for the new season of American Idol after making her return to the reality show.
She is also busy working on her next studio album and was recently seen in the recording studio with 'Blurred Lines' man Robin Thicke.
