Jennifer Lopez got “On The Floor” during a recent concert … and, she got on some dudes, too — hitting some sexually suggestive poses with her dancers.

The singer-songwriter took the stage at the Cook Music Festival on Tenerife — an island off the coast of Spain — Saturday night … and, she put on a raunchy display for the crowd.

Check out the video … J Lo’s crawling all over the stage — nearly locking lips with one dancer before bending over and backing it up on another’s crotch.

Tons of pop stars are dropping into highly sexualized poses during shows these days … with Sabrina Carpenter specifically gaining attention for it. Jennifer recently showed how crazy she could get, too … kissing her backup dancers at the American Music Awards.
