Six weeks after announcing her separation from Black Crowes frontman Chris Robinson, 39, on August 14, Kate Hudson is ready to make the split stick. "She is filing for divorce imminently," a friend tells Us Weekly. A major motivation: You, Me and Dupree costar Owen Wilson, 37.

"As soon as she files, it relieves a lot of the pressure of going out with Owen," says a friend of the actress, who has shared dinners, soccer games and a trip to Hawaii with Wilson recently.

The actor "makes Kate laugh," says a source. "She's much more true to herself when she's with Owen." Hudson's still in contact with Robinson about their son, Ryder, 2. "Chris calls and checks in," says the source. "Kate has never been happier." (Reps for Hudson and Wilson had no comment.)
