Time for Twigs! Rising star FKA twigs made her big U.S. television debut on Tuesday, Nov. 4, when she rocked the stage of The Tonight Show with Jimmy Fallon

The acclaimed British singer, who happens to be Robert Pattinson's girlfriend, appeared on the airwaves for the first time stateside to play her new material. 

"Our next guest has one of the most critically acclaimed albums of the year with her full-length debut LP1," Jimmy Fallon gushed of Twigs. "She's making her American TV debut with us tonight!"

Born Tahliah Barnett, Twigs took the spotlight to give a haunting and impressive performance of "Two Weeks," the first single off of her debut studio album. The singer, 26, previously released two EPs in 2012 and 2013.

Accompanied by swaths of fabric and wind machines, Twigs slinked across the stage and crooned the lyrics to her big single. 

Us Weekly exclusively revealed this past September that the "Pendulum" singer is dating Pattinson, 28. The stars began dating this past summer, and have been seen together out and about in Europe in the months since. 

"Tahliah thinks he is unbelievably handsome," a source told Us about Twigs' feelings for the Maps to the Stars actor.
