Jennifer Lopez has been photographed with Casper Smart, who she is reportedly to be dating.

The 42-year-old singer - who split from her husband of seven years Marc Anthony in July - has been spotted out with the dancer on a number of occasions, but friends have played down reports they are in a serious relationship.

One friend told People magazine: "Yes, they are dating and having a good time. They've been getting more open with their flirting for weeks. It's a fun fling. It's not meant to turn into anything more."

The brunette beauty - who has three-year-old twins, Max and Emme, with Marc - was with Casper on Friday night (11.11.11) when he performed at one of her concerts.

The dancer - who has previously appeared in 'Glee', 'Step Up 3D' and 'How I Met Your Mother' - wrote on his Facebook page: "In Palo Alto Bout to do a show w/ Jennifer Lopez for some1s birthday. (sic)"
