Jennifer Lopez Kisses Back-up Dancers at AMAs, After Ben Affleck Divorce

Ben Affleck? Yesterday’s news. Jennifer Lopez was all about getting it on at the AMAs — kicking off the show by locking lips with her backup dancers right on stage.

Yup, Jenny from the Block had the crowd on lock — puckering up with one male and one female dancer while tearing through a medley of the year’s biggest hits at Vegas’ Fontainebleau on Monday.

It was seriously steamy — lights dimmed, cameras swirling, and J.Lo serving up a whirlwind of PDA before getting a little touchy-feely with a few more dancers.

Looks like Ben was the furthest thing from her mind during that performance — J.Lo absolutely slayed and, honestly, seemed to be having the time of her life after what’s been a rough year personally.

Ben and J.Lo officially wrapped up their divorce earlier this year — and if there was any bad blood, it’s ancient history now.

The movie star’s been praising her on the red carpet lately, but you’ve gotta wonder — is he really cool with her officially kissing him away that quick?
