Did Robert Pattinson do something to make his fiancee flip out?

On Monday, the actor and FKA Twigs attended the 2016 MET Gala in New York where, strangely enough, Pattinson's infamous ex-girlfriend Kristen Stewart also showed up. While this would come off as uncomfortable for the exes, it appears that they're on good terms.

According to Tuesday's report from Hollywood Life, Stewart and Pattinson were actually happy to see each other and even took a moment to hug. But how did Twigs feel about this?

"[Kristen] was just overjoyed to see Rob. They both were happy to see each other. It had been a long time," a source told the site. "Kristen and Rob gave each other a big hug. Rob and Kristen were genuinely happy to see each other. Maybe a little too happy for Tahlia's [Twigs'] liking."

There's been some speculation that Pattinson and Twigs have been dealing with relationship issues for a while. A previous report from In Touch claimed the actor was feeling "trapped" with her and they were "fighting all the time."

"[She] isn't the girl for him," a source said. "She's very jealous and he was sick of having to explain himself. He's still young and just decided he wasn't ready to settle down."

At this point, anything could be possible, but based on the photo above of Pattinson and his British singing fiancee, it appears they are still very much together.

Stewart has reportedly moved on from her ex with French singer Soko. There was also a rumor that the actress was dating her gal pal Alicia Cargile although that never became official truth.

Stewart and Pattinson were one of the biggest celebrity couples in Hollywood after they met while filming Twilight.
