The singer, 44, who just finalized her divorce from Marc Anthony, was seen getting cozy with Dancing with the Stars’s Maksim Chmerkovskiy at Shrine nightclub at the Foxwoods Casino in Connecticut after her performance at the resort on Saturday, PEOPLE has confirmed.
“He went to see her perform, and then they went to Shrine after. They were flirting. They were dancing very close. I don’t know if they kissed. They had a lot of fun together,” says a source.
But the pair parted ways after their fun evening together – Chmerkovskiy left the club alone, according to the source.
The pair have denied dating rumors, and the DWTS winner Tweeted a message suggesting he didn’t appreciate the media frenzy that ensued when news leaked that he and Lopez may be dating.
“I’ve got 4 words for everyone: LIVE AND LET LIVE! NAMASTE Y’ALL,” he wrote.
Lopez and Chmerkovskiy met through mutual friends Leah Remini and her DWTS partner Tony Dovolani.
“They are friends and have been talking,” a source told PEOPLE earlier this month.
