SOME CHICK BASHES BAM MARGERA IN THE HEAD WITH A BASEBALL BAT!

"Jackass" star Bam Margera was knocked down on his own derriere when a woman hit him in the head with a baseball bat Saturday morning outside a bar he owns, TMZ reported.
The 31-year-old former professional skateboarder turned MTV sensation was hospitalized after the attack - which occurred during an early morning fight outside The Note bar in West Chester, PA.

The unidentified woman was arrested and charged with assault, according to the TMZ.

Margera has been in and out of the gossip tabloids in recent years due to his Jackass-inspired lifestyle. In July 2009, he was hospitalized after reportedly binging on alcohol for several days.

Margera's condition after the bat attack was not immediately known.
