Robert Pattinson and Kristen Stewart had broken up years ago. Both have moved on with their careers and personal lives - Robert Pattinson is engaged to FKA Twigs, while Kristen Stewart is in a relationship with her assistant, Alicia Cargile.

However, recent rumors claim that FKA Twigs is purportedly not convinced that everything's done between her fiance and his ex-girlfriend.

According to a recent report, FKA Twigs purportedly doesn't want any of Robert Pattinson's "Twilight" co-actors to be at their wedding, possibly avoiding any person who might remind of his groom about Kristen Stewart.

Is FKA Twigs worried about the possibility that Robert Pattinson could go back to Kristen Stewart?

There are rumors that the British singer may be anxious right now that her fiance could have a run in with his ex at the Venice International Film Festival in September.

"Both Kristen and Rob are on the list of attendees since the films they are starring in will be shown at the 72nd annual film festival," Hollywood Life reported. "However, seeing as the festival is from September 2nd to the 12th, the actress might not even see her former beau."

Kristen Stewart and Robert Pattinson's relationship crumbled back in 2012 when the "Twilight" actress was involved in a cheating scandal with her "Snow White And The Huntsman" director, Rupert Sanders.

Aside from Robert Pattinson, FKA Twigs allegedly has another reason to have a beef with K-Stew. Thr British music artist purportedly believes that Kristen has been badmouthing her to Kanye West.

"Twigs thinks that Kristen is trying to sabotage her career, by buddying up with Kanye West and bad-mouthing her to the rapper," an insider said, according to Celeb Dirty Laundry.

"She thinks Kanye is a big deal, and it is killing her that he is friends with Kristen. Twigs is scared that Kristen is basically turning Kanye against her, and that could kill her career."
