It seems like Robert Pattinson has already moved on from ex FKA twigs. The "Twilight" actor was seen holding hands with a mystery blonde when attending Seth MacFarlane's annual holiday party in Los Angeles on Saturday, December 9.

A source told Us Weekly, "They were together all night." The source further added that s/he witnessed them "holding hands" at the star-studded bash.

The bash was attended by the likes of Ansel Elgort, Kate Hudson, Chord Overstreet, Glen Powell and Nick Viall. Also among the attendees were Lea Michele and boyfriend Zandy Reich.

The news comes just weeks after the 31-year-old ended his relationship with former fiancee twigs, whose real name is Tahliah Debrett Barnett, after three years together. It was said that long distance relationship was the reason why they called it quits.

Pattinson and twigs started dating in September 2014, before the actor popped the question seven months later. "They were almost inseparable for their first two years together. But in recent months they have really started to drift apart and have been spending less and less time together," an insider previously spoke of the notoriously private couple.

"Rob is tired of it, has called off their engagement and told friends they have split," continued the insider, before adding, "With so much history between them, though, there are still strong feelings there." The source concluded, "It's a difficult situation but things have become tough between them for some time and they both know they were no longer working as a couple."

The "Good Time" actor left people wondering if he was still with the 29-year-old songstress when he said that he was "kind of" engaged to the singer in an interview back in July. He gave her glowing praise in the interview, though, saying that "she's super-talented and from a totally different world."
