Fans of "Twilight" stars Robert Pattinson and Kristen Stewart could still not get over the fact that he's now with FKA Twigs.

As a result, they are attacking the British singer with reckless abandon.

A Twitter fansite has some harsh words for FKA Twigs. The tweet read, "Never seen anyone so manipulative. Disgusting that she's managed to attach herself to Rob. #FKAtwigs #parasite."

In an interview with New York Times, FKA Twigs admitted that it's quite difficult to date somebody as famous as Robert Pattinson.

"[It's really hard - I can't begin to explain how awful it is. It makes you want to just stop everything sometimes. It makes you want to smash your face into the mirror," she said.

But all that comes with the territory in dating Kristen Stewart's ex Robert Pattinson, and FKA Twigs realized that. As the singer told NY Times, "I didn't see my life going this way at all. But it's worth it. I'm so happy...Nothing can impale my work or make me choose not to say things a certain way or make an image the way I want."

Celebrity Dirty Laundry, meanwhile, alleged that FKA Twigs has become paranoid of Kristen Stewart sabotaging her career, particularly after the "Twilight" actress was seen hanging out with Kanye West during the Paris Fashion Week.

"She thinks Kanye is a big deal, and it is killing her that he is friends with Kristen. Twigs is scared that Kristen is basically turning Kanye against her, and that could kill her career," the source claimed.

Robert Pattinson split with Kristen Stewart after the latter was caught cheating with Rupert Sanders, her director in "Snow White and the Huntsman." They tried to work out their relationship to no avail. The "Twilight" actor moved on with FKA Twigs while the actress has reportedly shacked up with her former assistant, Alicia Cargile.
