And we thought Rob Pattinson fans were crazy!
During a book signing in London on Wednesday, pop star Leona Lewis was punched in the head by crazed fan, Peter Kowalczyk. After the altercation, security immediately wrestled Kowalczyk to the ground, where he continued laughing as they charged him with assault.
Kowalczyk was taken by authorities to a location for mental health patients and was questioned for psychiatric assessment. His court hearing will be at the end of the month.
The clash left Leona bruised and a bit shaken and forced her to cancel a BBC performance that night to recover. On a positive note, her much anticipated sophomore album, Echo, will premiere in the US next month.
