Rihanna Responds to Billboard's Letter About Chris Brown

Rihanna arrives at her hotel on Friday (February 17) in London, England.

The 23-year-old pop star later smiled her way out of the building wearing a camouflage jacket.

Billboard recently wrote an open letter to Rihanna, questioning her rumored partnership with Chris Brown on her “Birthday Cake” remix.

“Three years and nine days later, it is officially implied that, no matter if you two are ‘single’ or ‘in a relationship’ or ‘it’s complicated,’ a token of forgiveness has been earned by Brown. And that’s not cool, to a whole lot of people,” writer Jason Lipshutz said.

“Chiefin’ while ppl spend hrs on letters… *kanye shrug* #phu–it,” Rihanna later tweeted, adding, “Who Jah bless I say NO MAN CURSE! Ting’s gettin better when they thought it would be worse … I’m so solid as a rock, they just can’t stop me now!”
