The Barbadian beauty is set to perform at the annual fashion show, as is Justin Bieber.
Along with the thigh-high black boots, Rihanna also wore a ‘Trackstar’ sweatshirt and an army fatigue coat.
The singer arrived in New York on Tuesday, after revealing that Chris Brown would be making a feature on her seventh album, ‘Unapologetic,’ set to debut on Nov. 19.
The song title is "Nobodies Business" and sounds like it will be about their on-and-off again relationship.
Earlier this year, three years after Rihanna and Brown broke up due his domestic assault, the pair caused controversy when she featured him on the remix of her song, "Birthday Cake." On the track, Brown sings, "Girl I wanna [expletive] you right now. Been a long time. I’ve been missing your body. Let me turn the lights down. When the window go down, it's a private party."
Rihanna has made no secret about her love for Brown, though he gave her a black eye and a swollen lip after a heated argument just three years ago.
"We love each other and we probably always will."
This past weekend, Rihanna tweeted, "Man my album is complete, and I need a [expletive] drink and a roll up! It was quite the journey, but it's all part of our story!”
