Robert Pattinson has put to rest rumours of a possible romantic reunion with his Twilight co-star Kristen Stewart by making a public appearance with fiancée FKA Twigs on December 10. They were spotted at the L.A. Dance Project Annual Gala in Los Angeles, and the pair looked smitten with each other.

Pattinson and Twigs, whose real name is Tahliah Debrett Barnett, have been together for nearly two years and the couple was said to have planned to get hitched before the year was up. But according to reports, Pattinson's closeness to his ex, Stewart, seemed to have caused a friction between the two, thereby pushing back their wedding date. It didn't help matters that Pattinson refused to acknowledge that a wedding was in the works.

However, contradictory to these claims, another source claimed that Twigs wasn't worried about Pattinson and Stewart possibly reuniting for yet another Twilight movie.

"Tahliah [FKA] has no problem whatsoever with Rob working with Kristen if they decide to film another Twilight movie," a source told HollywoodLife. "She doesn't feel threatened by Kristen, especially with the revelation that she is madly in love with her girlfriend."

At the time, Stewart was in a committed relationship with Alicia Cargile. But that relationship did not work out, and the actress is currently involved with singer St. Vincent.

"As far as Twilight is concerned, if this is something Rob really has his heart set on, she will of course support his decision," the source added.

Stewart and Pattinson dated for almost four years after meeting on the sets of the first Twilight movie. They parted ways after Stewart cheated on him with her Snow White and the Huntsman director Rupert Sanders.
