Listen to Jennifer Lopez's new song, 'Dance Again,' featuring Pitbull.

I'm sorry -- but is Jennifer Lopez really in her 40s? That dewy skin! Like, how? Sorry, sidetracked by her mind-blowing beauty. What's important at the moment is that she just dropped "Dance Again," another club banger, featuring Pitbull.

If you recall, this isn't Jennifer Lopez's first time at the Pitbull and RedOne rodeo either. Her previous smash, "On The Floor," also boasted a cameo by Mr. Worldwide and had RedOne's million-dollar production all over it. If it ain't broke, don't fix it right?

On "Dance Again" J. Lo's eager to get her fans moving. Layered in between lush and booming synths, RedOne's pulsating track makes this record a guaranteed summer smash. You might also wanna throw it on your gym mix if you're interested in burning say, an additional 2,000 calories per day. Up to you.

Pitbull opens the track, and as always, Mr. Worldwide raps about how easy it for him to get hot chicks to go home with him. "I'm an ol' dirty dog all day/No way José /Your girl only go one way/Ay Mi Madre/You should check that out." La Lopez is up next, and in rich, three-part harmonies she urges: "Only got this one life I've learned/Who care what they're gonna say/Lets' do it do it do it/I wanna dance, and love, and dance again." Good advice, lady. I'm down to just dance and love all day, but I might need some snacks/sustenance in between. What? I'm a snacker, and I don't see why I should have to apologize for it.
