We already knew Rihanna and Chris Brown were recording a duet, but after listening to their new tune, critics and fans can't stop talking about the sexually explicit lyrics!

On the track "Birthday Cake", Brown sings, "Girl I wanna f*** you right now. Been a long time I been missing your body. Lemme, lemme turn the lights down. When I, when I go down it's a private party." Woah! Wasn't this the guy who allegedly bashed her face almost three years to the day?

While the two insist that they're just friends, Chris went to RiRi's 24th birthday party last week and there have also been reports that they recently hooked up. "Rihanna loves to live dangerously," a Rihanna pal tells Us Weekly. "Talking to and hooking up with Chris is all part of that."
