Kristen Stewart and Robert Pattinson News Update: Vampire Couple's Sex Scenes May Break FKA Twigs Engagement

Trouble is brewing in Actor Robert Pattinson's paradise. The actor recently had his first major face-off with fiancé FKA Twigs, driving speculation that their engagement may not survive until their planned summer marriage.

Ok Magazine which broke the news that not all is well with the couple, attributed their troubles to media and Pattinson's Twilight co-star Kirsten Stewart. Twigs is unable to handle all the media attention around her relationship with her fiancé and has reportedly told him that it is getting to her.

"She's been ripping into Rob, telling him she didn't sign up for this media circus and saying she had no idea it was going to be this bad. It's all gotten too much for Twigs," a source told the magazine.

British singer Twigs a.k.a Tahliah Debrett Barnett has reportedly been receiving hate mail from 'Twilight nut jobs' and is stressed by Pattinson family disproval of the couple's engagement.

She also told-off Pattinson's former flame Stewart from talking about him in public. Stewart's description of sex scenes with the actor on the sets of Twilight has not amused the singer, Design & Trend reported.

"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 [director] Rupert Sanders. It was pretty brutal," the source said.
