Joining a bevy of talent to celebrate the season finale of "The Voice," Rihanna performed "Diamonds" on the two-hour finale episode on Tuesday night (December 18).
Making for an unforgettable final evening, the remaining three contestants performed with some big-name stars.
Cassadee Pope sang a number with Avril Lavigne, while Terry McDermott belted one out with British rocker Peter Frampton, and finally Nicholas David matched voices with Smokey Robinson.
In addition to letting the contestants shine, Bruno Mars, newly engaged Kelly Clarkson, and The Killers were also on hand to join in on the night's star-studded performances.
Looking forward to gracing the stage with all that talent, Rih-Rih tweeted earlier in the day, "Watch me perform tonight on The Voice, for the very first time..."
