Shia Lebeouf Margaret Qualley

Shia LaBeoufwas seen locking lips withMargaret Qualleyjust over one week since his exFKA twigsfiled alawsuit against him alleging “relentless abuse.”

TheTransformersactor, 34, and Qualley, 26, were photographed kissing in Los Angeles on Saturday, Dec. 19, after he picked her up from the airport, embracing as he helped her into the truck.

“What I went through with Shia was the worst thing I’ve ever been through in the whole of my life,” Barnett said in an interview withThe New York Times. “I don’t think people would ever think that it would happen to me. But I think that’s the thing. It can happen to anybody.”

LaBeouf addressed the allegations in several emails to the newspaper, saying he was in no position “to tell anyone how my behavior made them feel.”

“I have no excuses for my alcoholism or aggression, only rationalizations. I have been abusive to myself and everyone around me for years,” he wrote toThe Times. “I have a history of hurting the people closest to me. I’m ashamed of that history and am sorry to those I hurt. There is nothing else I can really say.”

In a different email, however, he said that “many” of the allegations were not true but explained he owed the women “the opportunity to air their statements publicly and accept accountability for those things I have done.”

Days after Barnett’s allegations made headlines, singer Sia accused LaBeouf of being a “pathological liar,” “conning” her “into anadulterous relationship claiming to be single.” The singer did not provide further details of her allegation and reps for both the singer and LaBeouf did not immediately respond to PEOPLE’s requests for comment.

“I believe he’s very sick and have compassion for him AND his victims. Just know, if you love yourself- stay safe, stay away,” added Sia, 45, whose 2015 “Elastic Heart"music videoLaBeouf starred in.

Sia went on to send amessage of supportto Barnett: “Also I love you @FKAtwigs. This isvery courageousand I’m very proud of you.”
