Robert Pattinson was caught kissing a mystery woman during a party in Beverly Hills this month, InTouch Weekly reported Wednesday, giving rise to speculation that he may be cheating on his fiancée FKA Twigs. The report also claimed that Pattinson and Twigs have been going through several problems in their relationship.

“Rob couldn’t keep his hands off this one girl. He was kissing her and putting his arms around her all night,” InTouch Weekly reported, citing an eye-witness, according to Gossip Cop. The witness also reportedly alleged that “Rob looked like he was into this girl. They seemed to have a lot to talk about and were really enjoying each other’s company.”

The InTouch Weekly report also claimed that Twigs has been concerned about her relationship with the "Twilight" star. Twigs and Pattinson sparked engagement rumors in April 2015 after rapper T-Pain revealed in an interview that the “Two Weeks” singer was engaged to the actor.

“She’s been worrying that he might have interest in someone else. Friends have been in Rob’s ear telling him it may be time to walk away… It’s really not looking great," a source told InTouch Weekly.

However, Gossip Cop debunked the report, saying that Pattinson was not cheating on FKA Twigs.

This is not the first time that rumors surfaced about trouble in paradise for the couple. Earlier this year, Hollywood Life reported that Twigs issued an ultimatum to Pattinson to marry her in 2016 or “kiss her goodbye.”
