Robert Pattinson and FKA Twigs reportedly ran into the actor's ex-girlfriend at the MET Gala this year.

On Wednesday, Hollywood Life reported that Pattinson's infamous ex Kristen Stewart greeted him and his new lover Twigs at the big event in New York last Monday. And while it would appear that this would create some drama or discomfort, the site said that Stewart is completely supportive of Pattinson and Twigs.

"Kristen just wants nothing but happiness for Rob, having hurt him all those years ago and she believes Taliah [Twigs] is just what he deserves," a source said. "From what she could see they are perfect for one another, and when they greeted each other it was all very pleasant and there was no animosity now because it's all water under the bridge."

Stewart and Pattinson faced some difficulties in the past when the actress allegedly had an affair with her Snow White and the Huntsman director Rupert Sanders. And while she might be happy for her former boyfriend now that he's found love again, the source said it was still "a bitter pill for her to swallow."

There was actually another report from Hollywood Life that claimed Pattinson and Stewart embraced when they ran into each other. She was apparently really happy to see him, but it seems the actor's current lover was not comfortable seeing this in front of her. In fact, she might've been a little upset.

"[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 liking."
