Jennifer Lopez and Maksim Chmerkovskiy say they're just friends, but they could smell each others pheromones judging from this pic ... obtained by TMZ.
JLo and Maksim were at the Foxwoods Casino in Connecticut Saturday night after her show. They hit up the Shrine nightclub and were certainly close.
This is like the millionth time they've been spotted together.
He was also the performer who lifted her up at the AMAs last year.
Judge for yourself.
