The 44-year-old singer and American Idol judge and 34-year-old Ukrainian Dancing With The Stars pro dancer and season 18 winner, who have recently sparked romance rumors, spent time together at a nightclub in Connecticut after one of JLO's concerts at Foxwoods Resort Casino in Mashantucket on Saturday, June 21, a source told E! News.
J.Lo and Maks were spotted in the VIP area of the venue's Shrine club, along with her entourage and one of his friends.
"They partied and seemed really at ease together," the source said.
Under tight security, the group celebrated one of the singer's crew members' birthdays and enjoyed Jameson Irish whiskey and Belvedere vodka.
Lopez had earlier in the day hung out with her mother and spent time at the hotel pool with her 6-year-old twins, Max and Emme, performed her show and had dinner with her dancers and crew at the Italian restaurant Alta Strada, located in the resort.
Chmerkovskiy and Lopez met in November 2013, when they performed together at the American Music Awards (pictured above). J.Lo, whose breakup with dancer Casper Smart was revealed on June 6, said during a Twitter chat on June 12 that she is not dating anyone. A difference source also told E! News that she and Makes are "friends."
