Twilight heartthrob Robert Pattinson and quirky singer FKA Twigs, real name Tahliah Debrett Brannet, are said to be tying the knot after six months of dating.

Pattinson, 28 and FKA Twigs, 27, have been virtually inseparable, and even exchanged promise rings earlier this year.

It was in fact rapper T-Pain that accidentally spilled the beans in an interview with Vulture magazine.

He said of FKA Twigs: "Well, the first time we even met each other, we met in the studio. "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 asked if the two were going to get married, he replied, "Yeah [she's engaged], to ol' Patty [Robert Pattinson]. I don't know if she wanted anybody to know that…"

He conveniently covered it up as an April Fools joke but sources close to the stars confirmed the news to MTV, People Magazine and Page Six in the United States.

We can't WAIT to see what FKA's wedding dress will be like. We already know what Pattinson looks like as a groom....
