The day after the singer slammed rumors that she's romancing the younger Dancing With the Stars pro, 34, the pair was spotted dancing together at Shrine Nightclub after Lopez' performance at Foxwoods Resort Casino in Connecticut, Us Weekly reports.
"Maks was whispering into her ear and hugging her," an onlooker told the magazine, adding that the two got down to tunes including Jay Z's "99 Problems" and Rihanna's "Birthday Cake." "They looked very flirty with each other. She had a huge smile on her face and looked like she was having a great time."
Though sources tell Us that the pair are "just friends," the onlooker caught the rhythmic twosome holding hands at the end of the night before saying goodbye.
Lopez, 44, looks like she's diving back into the dating pool fast: She just announced her split from dancer boyfriend of nearly three years, Casper Smart, 27, two weeks ago, and officially ended her divorce from ex Marc Anthony, 45, on June 16.
