Robert Pattinson and FKA Twigs fighting?

Are Robert Pattinson and Tahliah Debrett Barnett a.k.a. FKA Twigs fighting? 

Recently, Barnett spoke with Complex magazine and said that she is "genuinely shocked and disgusted" by the social media attacks aimed at her, some of which come from Pattinson's fans. 

"It is pretty horrible," she admitted. "But ultimately, I'm in an amazing relationship. So it doesn't matter." 

The 27-year-old singer has always been candid about the struggles of dating a famous movie star and how some people have bullied her online. Now, it looks like Barnett has had her first major fight with her fiancé, and it's reportedly about all the harassment that she has experienced since they started dating. 

According to OK! Magazine, Barnett is still not coping well with the pressures of being in the public eye as part of her relationship with the "Twilight" actor. A source told the magazine that the singer has been fighting with Pattinson, telling him that "she didn't sign up for this media circus and saying she had no idea it was going to be this bad." 

The insider added that the media intrusion in Barnett's life along with the hate mail from some "Twilight" fans have been sparking arguments with the actor. Reportedly adding to the couple's discord is his ex, Kristen Stewart, allegedly spreading poisonous rumors about Barnett. The source also points to Pattinson's family as one of the reasons for their constant fights as the magazine's source claimed that they have never really approved of their engagement. 

"It has gotten too much for Twigs," said the source. 

Last week, the magazine reported that Barnett was angry that Stewart spoke out about Pattinson and their intimate scenes in "Twilight" and sent her a message to stop talking about the actor or their past. 

"She sent a message to Kristen to shut up about Robert because she lost the right to speak about him in public," another source told the magazine.
