The Hellboy star filed papers in a Los Angeles court Tuesday, November 5 against his longtime wife Opal Stone Perlman.
The filing comes just days after In Touch exclusively revealed the actor was spotted without his wedding ring and then on a lunch date with actress Dunbar over the weekend.
The duo dined at Soho Warehouse, which sparked romance rumors between the two.
“They definitely seem like an item,” a snitch told the site, adding, “They were very touchy-feely.”
The two married in 1981 on Valentine's Day. They share a son and a daughter, both of whom are adults now.
