Robert Pattinson was defended by Tahliah Barnett aka FKA Twigs. According to a report from Ok Magazine, the "Two Weeks" singer slammed her fiance's ex-girlfriend, Kristen Stewart, for talking about the "Rover" actor.

The alleged confrontation took place after Robert Pattinson, who is engaged to Tahliah Barnett aka FKA Twigs, was mentioned by his former flame in a recent magazine interview. In the feature, Kristen Stewart described his sex scenes with the "Twilight" actor as "agony and grotesquely uncomfortable."

The statement reached Robert Pattinson and Tahliah Barnett aka FKA Twigs, and the latter allegedly lashed out at Kristen Stewart.

"She sent a message to Kristen to 'shut the f**k up' about Robert because she lost the right to speak about him in public 'the moment she got into that car with Rupert Sanders,'" an insider revealed.

"It was pretty brutal."

"It will be a very long time before Kristen talks about Rob again in public," the source added.

Robert Pattinson supposedly opened up to Tahliah Barnett aka FKA Twigs about how Kristen Stewart cheated on him with her married "Snow White and the Huntsman" director, Rupert Sanders.

"That whole nightmare [made him want] "to quit acting forever," an insider revealed.

Since then, Robert Pattinson has moved on with Tahliah Barnett aka FKA Twigs.

"[She is] Rob's fiercest defender," a source claimed.

According to a report from New York Times, the eccentric singer admitted to the downside of dating the hunk actor.

"It's really hard," FKA Twigs said, referring to haters who have been harsh on her ever since she and Robert Pattinson began dating.

"It makes you want to just stop everything sometimes. It makes you want to smash your face into the mirror."

Nonetheless, Robert Pattinson and Tahliah Barnett aka FKA Twigs remain strong amid all their haters.

"I didn't see my life going this way at all... But it's worth it. I'm so happy," the 27-year-old singer clarified.
