Did T-Pain Just Reveal Robert Pattinson and FKA Twigs Are Engaged?

Splash News

Singer T-Pain might have just let a huge secret out of the bag.

In a new interview with Vulture, the Auto-Tune innovator says that British singer FKA Twigs, 27, is engaged to her boyfriend, actor Robert Pattinson. The buzzworthy artist was first spotted with the 28-year-old Twilight star in September.

T-Pain lets the bombshell drop when he's asked if he's collaborating with FKA Twigs on his new album, whom he names as one of his favorite artists right now. But the "Bartender" singer says that it will be hard for her to find the time.

"But she’s on tour so much, and anytime I call her, she’s in a different place," he says. "And she’s engaged now, so that’s about to be a whole other thing."

Wait, what?!

"Yeah, to ol' Patty [Robert Pattinson]," he confirms when he gets called out on revealing the big news. "I don’t know if she wanted anybody to know that … "

Though perhaps the news shouldn't be surprising, given that the couple appeared to be getting serious quickly. FKA Twigs was spotted in London over the holidays, which she presumably spent with Pattinson and his family.

"They absolutely loved her," E! Newsreported of the "meet the parents" moment. "It went so well. Rob's family has always been supportive of him and they thought they were great together."

In December, the usually private singer opened about Pattinson in an interview with The Guardian, calling him the "man that [she] loves."

"That side of my life [the paparazzi] is nothing to do with me," she told the British newspaper about the constant scrutiny on their relationship. "That's like… That is the… side of life of the man that I love. ... I look uncomfortable because I am uncomfortable. But then it's like, is this person in my life worth that? And he is, without question... In comparison to how happy I am. And how I feel with him. It's 100 percent worth it."

And clearly, the two make a gorgeous couple. Check them out last month at the BRIT Awards, where she was spotted sitting on his lap.

After the interview was published, T-Pain later claimed his accidental reveal was an April Fools' joke -- though Peoplereports that the two are in fact engaged.
