Jennifer Lopez is reportedly dating dancer Casper Smart.
The singer-and-actress -- who split from her husband of seven years Marc Anthony in July -- has enjoyed several romantic evenings out with Casper, although friends insist it isn't serious.
One pal 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."
Casper -- who has appeared in "Glee," "Step Up 3D" and "How I Met Your Mother" -- joined J.Lo on Friday night at one of her concerts.
He wrote on his Facebook page: "In Palo Alto Bout to do a show w/ Jennifer Lopez for some1s birthday. (sic)"
Jennifer -- who has three-year-old twins, Max and Emme, with Marc -- was recently linked to actor Bradley Cooper and the pair were said to have gone on several dates.
The 42-year-old beauty recently admitted she is an "eternal optimist" about romance, despite her marriage break-up, and is confident she will find love again.
Jennifer -- who has been married three times and had high-profile relationships with P. Diddy and Ben Affleck -- said: "I really wanted this family to work. That was my biggest dream, and I worked hard at it. We both did. Sometimes it doesn't work -- and that's sad. But I remain an eternal optimist about love. I believe in love. It's still my biggest dream."
