Billy Baldwin was photographed with a mysterious head abrasion nearly one week after he began feuding with Sharon Stone.

The protruding red wound above the “Backdraft” star’s left eyebrow was visible Monday night as he left Craig’s restaurant in Los Angeles.

Nonetheless, Baldwin, 61, seemed to be in good spirits as he smiled for photographers and even stopped to sign autographs for fans.

The “Gossip Girl” alum walked by himself and wore a striped button-down shirt with blue jeans and gray sneakers.

It is unclear how he sustained the injury, which appeared to be scabbing.

His manager did not immediately return Page Six’s request for comment.

The outing comes a week after he called out Stone.
Baldwin made headlines last week when his “Sliver” co-star Stone, 66, claimed late producer Robert Evans had encouraged her to have sex with the actor to improve their onscreen chemistry and “save” the 1993 movie.

“He’s running around his office in sunglasses explaining to me that he slept with Ava Gardner and I should sleep with Billy Baldwin, because if I slept with Billy Baldwin, Billy Baldwin’s performance would get better, and we needed Billy to get better in the movie because that was the problem,” the actress said on “The Louis Theroux Podcast” on March 11.

Soon after Stone’s story went viral, Baldwin fired back at her with a long, threatening message on X.

“Not sure why Sharon Stone keep [sic] talking about me all these years later? Does she still have a crush on me or is she still hurt after all these years because I shunned her advances?” he began on March 12.

The “Forgetting Sarah Marshall” actor claimed he has “so much dirt” on the “Basic Instinct” star that “it would make her head spin,” but he has “kept quiet.”

“The story of the meeting I had with Bob Evans imploring him allow me to choreograph the final sex scene in the photo below so I wouldn’t have to kiss Sharon is absolute legend. Wonder if I should write a book and tell the many, many disturbing, kinky and unprofessional tales about Sharon? That might be fun,” he concluded.

Baldwin has since been photographed out and about on several occasions — including with his wife, Chynna Phillips.

The couple, who have been married since 1995, appeared to be having an intense conversation on March 14 in photos obtained by Page Six.

Meanwhile, Stone has continued to attend public events without addressing her co-star’s scathing response.
