We have some bad news for "Twilight" fans hoping against hope that former costars (and former flames) Robert Pattinson and Kristen Stewart would one day get back together: Pattinson is reportedly engaged to British musician FKA twigs.

The news was broken by an unexpected source: rapper T-Pain, who accidentally revealed the hush-hush engagement during an interview with Vulture. Talking about influences on his new album, T-Pain said that he's a huge fan of twigs -- but probably wouldn't get the chance to work with her anytime soon, because she's busy planning her wedding.

"[S]he's engaged now, so that's about to be a whole other thing," the rapper said of the perpetually-busy songstress.

When pressed about that bit of information, T-Pain told Vulture, "Yeah, to ol' Patty [Robert Pattinson]. I don't know if she wanted anybody to know that ..."

Apparently, T-Pain really wasn't supposed to let the cat out of the bag, and later tried to play off his gaffe as an April Fools' joke. But People reported on Wednesday that that the pair is indeed engaged, citing two anonymous sources as proof.

Reps for Pattinson and twigs are staying quiet about the news for now, though People reports that the pair -- who have been dating for about six months -- had previously exchanged promise rings, and reportedly live together.

No word yet on how Stewart -- or millions of "Twilight" 'shippers -- is taking the news.
