17. "What's My Name" (feat. Drake) (2010)
Rihanna's on-off relationship with Drake has made for rich tabloid fodder ever since the Canadian rapper added a verse to this Number One hit. "What's My Name?" was originally cut from her 2009 album Rated R; but as his star rose, the StarGate and Kuk Harrell–produced remix of what was originally a solo Rihanna showcase eventually appeared on to 2010's Loud. "Drake is the hottest rapper out right now and we've always been trying to work together," Rihanna told Billboard that year. In fact, it's Drake's voice we hear after the chorus: "Yeah, I heard you good with those soft lips/Yeah, you know word of mouth." She responds in kind: "Not everybody knows how to work my body/Knows how to make me want it/But boy you stay up on it." It's a whirlwind of mutual flirtation they've kept alive ever since.
