The R&B singer, fresh off an appearance at last night's BET Awards, debuted the new song Monday (June 30) - and rather than relying on his own star power, Brown's sure to get everyone talking with a pair of guest spots on the song.

The synthed-out slow burner is at first a Brown tune that recalls some of Usher's vast discography. That, it turns out, is no coincidence - on the second verse, Usher himself appears to drop his vocal on the track, echoing Brown's sentiments about this new girl that neither wants to let go.

To cap it off, Rick Ross storms in with a rap on the song's bridge, throwing out enough New York Yankees and baseball references to stock an entire album. "Baby I'm a boss, I'm talking George Steinbrenner," Ross raps, with mentions of Yogi Berra and Derek Jeter as well.
