Preview of 'Back Together' artwork

Robin Thicke and Nicki Minaj have gotten "Back Together" for a new collaboration, a reunion of sorts after their 2009 track “Shakin’ It for Daddy."

This latest track finds Thicke unsurprisingly singing about a lost love, while Minaj throws in a shout out to a presidential contender. “Used to call me Hillary ’cause I Rodham,” she quips.

The song was released Wednesday night on iTunes, hours after false rumors surfaced that Thicke might be engaged to his 20-year-old girlfriend.
