Club goers noticed an "undeniable spark" between the new couple.
Get your freak on, Jennifer Lopez! Clearly taking full advantage of her newly single status, the singer and American Idol host got frisky with her rumored new beau, 24-year-old dancer Casper Smart, at a Las Vegas club this week.
"They were flirting," the witness tells Us Weekly. "Casper even came over and gave her a lapdance. She was giggling as he gyrated on her."
Lopez reportedly began dating Smart a few weeks ago, after he danced backup for the mom of two at her San Francisco show. The couple have since been spotted in New York. While Lopez refuses to comment on the fling, she did coyly tell Ryan Seacrest earlier this week, "I'm a busy girl."
Since announcing her split from Marc Anthony this past summer, Lopez has been linked with several men, including People's Sexiest Man Alive, actor Bradley Cooper.
