If Jennifer Lopez and Maksim Chmerkovskiy want people to believe they aren't dating, they aren't doing a very good job.

J. Lo and the Dancing with the Stars pro were seen together in Connecticut, where Lopez had a show at the Foxwoods Resort Casino. Following her live performance, Lopez still had the energy to party at the Shrine Nightclub in the resort with Maksim.

A source who was at the club tells Us Weekly, "Maks was whispering into her ear and hugging her. They looked very flirty with each other...She had a huge smile on her face and looked like she was having a great time." A source told E! something similar, sharing, "They partied and seemed really at ease together."

The news comes as a surprise, as J. Lo has been adamant to claim she's single and not seeing anyone. Since rumors of her and Maks getting together started earlier this months, reps have denied the story and J. Lo tweeted, "No I'm Not. #rumors #nottrue."

We suppose Maks makes a nice chaperone for a single lady and it's worth noting he owns a dancing studio in Stamford, Connecticut and owns a home in New Jersey – so it's not like he's jetting out across country just to hang out with a friend.

Still, it's hard to think of a better partner for J. Lo to bounce back with, after her sudden breakup from Casper Smart.
