Rihanna, the Barbadian-born reigning princess of the U.S. pop and R&B scene, brought down the house on the season finale of “X-Factor” Saturday, Dec. 11, in London. She and finalist Matt Cardle took the stage together to sing one of her past hits, “Unfaithful.” She also performed her newest hit from her CD “Loud,” titled “What’s My Name?”.

Cardle went on to win the show following the steamy performance. Rihanna appeared on the show a month ago and sang her hit “Only Girl (In The World).” For the performance with Cardle, Rihanna wore a tight, long black dress with a thigh-high slit.

The performance likely hit the right note with U.K. fans and came at a good time, as the singer is preparing to perform a series of concerts
in the country.
