Comedian Seth MacFarlane hosted his star-studded annual holiday party in Los Angeles on Saturday (9 December). And, as always many of your favourite stars attended the bash.

According to Us Weekly, Kate Hudson, Sia, Eric Dane, Lea Michelle, Nick Viall, Ansel Elgort and Chord Overstreet were some of the guests who were spotted arriving for the party.

One celebrity made headlines with his appearance at the party. It was none other than Robert Pattinson.

The Twilight star, 31, made heads turn as he was spotted flaunting a lot of PDA with a mystery woman at the party, according to the report.

"They were together all night," the source told the celebrity news website. "I saw them holding hands."

Is the British actor dating again? As of now, it is unclear as to whether he has found someone special after splitting with singer FKA Twigs (real name Tahliah Barnett) in September after three years of dating. Pattinson, who dated his Twilight co-star Kristen Stewart between 2009 and 2012, was last spotted with his former fiancé in public at the 2017 Cannes Film Festival in May.

A source previously told The Sun, "They were almost inseparable for their first two years together. Rob is tired of it, has called off their engagement and told friends they have split. With so much ­history between them, though, there are still strong feelings there."

"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 source added.

The reason for the split was said to be their hectic travel schedules that "took a big toll on the relationship".

A source previously told E! News that Pattinson was the one to end the relationship. "They bought a house together but then it was just not working out between them," the source said. "She moved out."
