US reports say the actor is now officially off the market after getting engaged to his musician girlfriend of six months.
Sources confirm to People that the engagement is official, although their reps have declined to comment.
News of their engagement surfaced after rapper T-Pain said FKA Twigs may not feature on his new album because "she's engaged now."
In an interview with Vulture, T-Pain said FKA Twigs was engaged to "ol' Patty [Robert Pattinson]. I don't know if she wanted anybody to know that."
However, soon after T-Pain took to Twitter to say that his quote on their engagement was apparently an April Fool's joke.
Robert and FKA Twigs - real name Tahliah Debrett Barnett - began dating last year, but the pair have kept their relationship away from the limelight.
