"Girl, I wanna f**k you right now/ Been a long time, I've been missing your body," Breezy sing his sexually-dripping lyrics. "Lemme lemme turn the lights down/ When I, when I go down it's a private party/ Ooh ooh, it's not even her birthday/ But I wanna lick the icing off."
Riri replies him by delivering her own suggestive lines, "Remember how you did it, remember how you did it/ If you still wanna kiss it, come come and get it/ Put a candle on my muthaf**kin back, baby blow it/ Daddy make a wish, put this cake in your face."
Rihanna is known for making bold statements, from her often sexually charged music to her tattoos to even the hue of her hair.
But her latest decision -- a musical pairing with the man who three years ago left her bloodied and bruised -- has left some questioning her judgment.
On Monday, after days of teasing, Rihanna and Chris Brown debuted two songs featuring each other. Brown sings and raps on the remix of Rihanna's sexually charged song "Birthday Cake," and she appears on a new version of his upbeat tune "Turn up the Music."
Fans have been split about the topic: Some support Rihanna and Brown's collaborations, others condemn it. The topic was still trending on Twitter on late Tuesday, with plenty of tweets criticizing Rihanna for embracing her former abuser.
Rihanna seemed to address the controversy Tuesday when she won best international female artist at the Brit Awards.
"At times when I feel misunderstood, my fans always remind me that it's OK to be myself," Rihanna said.
But Bill Werde, editorial director of the music trade publication Billboard, says Rihanna's decision to make music with Brown could disappoint some of her supporters.
"I think there are people out there that feel betrayed (by) Rihanna," he said. "She has every right to be an individual ... she has every right to date who she wants to date and be with whoever she wants to be with. She's a grown woman. But you just need to recognize that then the fans have every right to feel how they're going to feel about that."
Emails to both Brown and Rihanna's record labels asking for more information on the songs went unreturned Tuesday, and while Rihanna's representative had no comment, Brown's publicist did not return a request for comment.
