Christina Aguilera & Tony Bennett 1
Aguilera and Tony Bennett recorded a duet of "Steppin' Out With My Baby" in 2006 and it appeared on his album Viva Duets in October of last year.
Pitbull & Priyanka Chopra 2
We all know Pitbull is pretty much the king of collaborations, but when this one with Priyanka Chopra came out earlier this summer, I couldn't help but feel confused. Talk about random!
Selena Gomez & Prince Royce 3
It was recently revealed that Gomez--who normally sticks to her more pop roots-- and Prince Royce teamed up and recorded a song together for his upcoming album!
Jennifer Lopez, Will.i.am, Mick Jagger 5
These three teamed up for will.i.am's song "T.H.E." Though the track didn't make it on the album, a video for the song was released. Talk about an eclectic combo!
Marc Anthony & Cypress Hill 6
Marc Anthony is featured on Cypress Hill's Armada Latina and apparently, even the duo themselves were surprised that he agreed to sing on the track. Ha! Pitbull also appears on the song.
