Rihanna was seen arriving at the 40/40 club - owned by Jay-Z - for a viewing party of the boxing match between Cotto vs Canelo.
The singing heavyweight attended the event with her rumoured new boyfriend Travis Scott.
Rihanna and Travis, 23, have been linked for a few months, after first being seen getting close at the singer's Fashion Week party in New York in September.
Rihanna has announced her new album will be called ANTI and released any day now.
Fellow singer Adele recently paid tribute to Rihanna, admitting she'd like to have her in her 'squad'.
She told Rolling Stone magazine: "I've heard about a squad. I wish my squad was all supermodels. We are, in our brains. I guess I have my own squad.. It's not as interesting as some of the other squads that are around right now. But maybe Rihanna can be in my squad! That would be really cool. Oh, God. She's life itself, isn't she? I love her."
