Leonard DiCaprio was attacked by a woman at a Hollywood party given by Paris Hilton's ex-boyfriend, People magazine reported on its Web site.

DiCaprio had been attending a party on Friday when a woman struck him with what appeared to be a beer bottle. He was taken to the hospital and required about a dozen stitches.

"The actor was in Los Angeles during a short break from filming The Departed. While leaving a small private gathering, Leo was attacked by a woman who was trespassing and had repeatedly been asked to leave the property," DiCaprio's publicist, Ken Sunshine, said in the statement.

It is reported that the woman was looking for an ex-boyfriend, not DiCaprio.
