OK! Exclusive: FKA Twigs Enraged With Robert Pattison For Calling Kristen Stewart

It may be an unhappy holiday season for FKA Twigs and Robert Pattinson because an insider revealed the engaged couple is fighting after Twigs found calls to Kristen Stewart on Rob’s phone!

The source told OKMagazine.com exclusively that FKA, 27, is mad at Rob, 29, for reaching out to Kristen, who is getting early Oscars buzz for her role in Clouds of Sils Maria.

“She confronted him about it straight away and he insisted it was just a good will congratulations call about Kristen being in the Oscar race this year,” the source said. “She’s not happy at all about this and isn’t really satisfied with his explanation.”

And while FKA is “not the jealous type at all,” according to the source, Rob’s relationship with his “first big love” KStew, 25, is the one thing that makes her green with envy.

Last holiday season, Rob and FKA were still in the early stages of their relationship and dealt with standard meeting the family drama. And now, it looks like they still can’t enjoy one happy holiday together.
