Enrique Iglesias and Jennifer Lopez engage in a little 'Mouth 2 Mouth' on a sexy new song from the repackaged edition of Iglesias' 'Euphoria' album.

Teaming together two of music's biggest names can be tricky because it creates high expectations, but 'Mouth 2 Mouth' lives up to that promise, with production from DJ Frank E, a driving synth beat, and lyrics about a primarily physical relationship.

"She's such a good waste of time / But in the back of my mind / You know you're all I'm thinking of," Enrique sings, leading into the hook, "I can't catch a single breath, baby, help me now /Hurry up, it's killin' me the way I need your mouth to mouth."

J. Lo takes the second verse and reveals her conflicted state of mind when she sings that the situation "feels like the wrong kind of right." 'Mouth 2 Mouth' sounds like yet another dance floor smash, following in the footsteps of Iglesias' earlier singles 'I Like It,' 'Tonight (I'm Lovin' You)' and 'Dirty Dancer.'

The new 'Euphoria' is expected to see a November release. Iglesias is in the middle of a tour with Pitbull and Prince Royce, while Lopez will return to the 'American Idol' judges' chair in January.
