Even though the source tells OK! magazine that the songstress is “not the jealous type at all,” she was still allegedly “enraged” to discover K. Stew’s name in her man’s recent calls.

“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 says. “[FKA twigs] is not happy at all about this and isn’t really satisfied with his explanation.”

The Twilight costars dated for years, only to call it quits in 2012 when she was caught having an affair with a then-married man, Rupert Sanders.

The source adds of Rob’s infatuation with his ex, “[FKA twigs] knows how hung up Rob was on Kristen and how hard it’s been for him to move on, so the fact that he’s gone and done this has totally unsettled her.”

Do you think this is the end for Rob and FKA twigs?
