The rapper, who recently announced she is retiring to start her family, was at the launch celebration for her new fashion line, Fendi Prints On, in Beverly Hills on Tuesday. She was accompanied by Kenneth Petty who also wore pieces from Nicki's collab with Fendi.
ET's Keltie Knight caught up with Nicki and she revealed that she and Adele are teaming up.
When asked if she'll be working with the 15-time Grammy award winner, Nicki replied: "Yes and yes, yes and yes, wooo hoo!"
She added: "But Adele made me swear to secrecy that I'm not allowed to tell anyone that I'm working with her. And that we already shot a video. And it's an epic song! Ahh!"
Adele has been an outspoken fan of Minaj for some time.
Also, at the Fendi Prints On event, Nicki gave out free $1000 pieces from her collaboration to fans.
