The Quantico star, 33, and Miles Brown collaborated for the tribute and they sang Prince's hit song "Kiss".
Priyanka was joined at the event by her co-star Johanna Braddy, and Miles attended with his on-screen parents Anthony Anderson and Tracee Ellis Ross.
The Indian actress' performance garnered mostly positive feedback, although a few social media users felt that the Prince tribute felt like it had been "shoehorned" into the act.
Prince died on April 21 at age of 57.
She has just wrapped filming her Hollywood debut Baywatch. The finale episode of the first season of Quantico aired on May 16.
