Mr. Blonde's London Meltdown

Reservoir Dogs star Michael Madsen was forcibly hospitalized in London following a row with a woman

Say it ain't so. Mr. Blonde has gone mental?

Michael Madsen, best known for playing the sadistic, ear-averse jewel thief in Quentin Tarantino's Reservoir Dogs, was forcibly hospitalized on Sunday after apparently going berserk and screaming at a woman in a London hotel.

According to U.K. media reports, the staff at the posh Dorchester called police after receiving complaints from guests about a disturbance coming from Madsen's room in the West End hotel.

Officers found the 49-year-old thespian "screaming and shouting" at a female companion. When Madsen refused to calm down, cops forcibly restrained him and he was taken by ambulance to a hospital, where he was treated for cuts and bruises before being discharged. He was not arrested.

The Hollywood tough guy, in London after wrapping work on the film The Big I Am, checked into the Dorchester on Saturday with a woman described as his wife and their 5-year-old daughter.

Madsen has been married to De Anna Morgan, his third wife, since 1996, and the couple have three children together (he has two from a previous marriage).

The actor is most often known for roles as big-screen heavies in such films as Donnie Brasco, Mulholland Falls, Kill Bill and Sin City. Other notable credits include Thelma & Louise, Wyatt Earp, Free Willy, Species and Die Another Day.

Madsen's rep, Liza Anderson, said she was aware of an incident but declined to comment.
