Robert Pattinson and FKA twigs are hit by reports that their relationship is in trouble. The Twilight actor and the 27-year-old singer are apparently fighting over Kristen Stewart.

According to In Touch magazine, the 29-year-old British actor wanted to support the 25-year-old actress at a NYC event, but twigs, whose real name is Tahliah Debrett Barnett, disagreed and a source said she is "jealous and insecure". An insider told Hollywood Life that twigs, "Went ballistic and screamed, 'No f***ing way'.

"Now, as his relationship with Twigs gets more volatile, he's feeling completely torn between the two women."

In 2012, Pattinson ended his relationship with Stewart after it was confirmed that she cheated on him with British director Rupert Sanders. Stewart and Sanders, who worked together on Snow White And The Huntsman, were photographed kissing in Hollywood hills.

The pair patched up differences and started dating again and were spotted together at the Coachella Music Festival in 2013. However, the two broke up in May 2013 after Pattinson pulled out of his 27th birthday celebrations planned by Stewart.

Meanwhile, during an interview with the New York Times, twigs talked about the increased media attention associated with dating the Hollywood actor. She said: "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."

"It's relentless. There's no amount of songs I can sing or dances I can dance that will prove to them I'm not a monkey. I didn't see my life going this way at all," twigs said and added, "But it's worth it. I'm so happy."
