However, the rapper later appeared to retract his claim, stating that it was all a rather elaborate April Fools Day prank - so what’s the truth?
Wonder how Rob will feel about being called "ol' Patty"?
During his chat with Vulture, which was published yesterday, T-Pain discussed whether he’d be collaborating with Twigs, real name Tahliah Debrett Barnett, on his upcoming album.
“Well, the first time we even met each other, we met in the studio,” he told the mag. “Her music’s changed a lot since then. But she’s on tour so much, and anytime I call her, she’s in a different place.
“And she’s engaged now, so that’s about to be a whole other thing.”
When the interviewer then pressed T-Pain on his comment, he replied: “Yeah, to ol’ Patty [Robert Pattinson]. I don’t know if she wanted anybody to know that…”
T-Pain then took to Twitter, posting this:
So, let’s just get this straight, T-Pain. You anticipated that the interview would be published on 1 April, and planted a quote about a fake engagement to fool everyone? Hmmm.
The couple’s reps are not commenting on the matter, but two sources have told US mag People that a wedding is on the cards.
Since they began dating in 2014, Rob and FKA have become almost inseparable and the actor joined his girlfriend on her recent tours of the UK and the States.
He was also present to support her at the Brits Awards, and they were also spotted rubbing shoulders with their A-list pals at one of the evening’s after-parties.
