Casey Kasem Feud--Members of legendary radio personality Casey Kasem's family are locked in a bitter feud with each other as the DJ battles Parkinson's disease, according to a U.S. report.

Kasem's wife Jean has reportedly blocked his three children from visiting their ailing father, according to TMZ.com, and Kerri, Julie and Mike Kasem have not been able to contact him for three months.

On Tuesday, Kasem's three children, along with friends and co-workers, protested the alleged lock-out during a camp-out in front of his house.

Kasem's brother has also joined the protest and tells TMZ.com that Jean has had a strained relationship with her stepkids for years - and that he hasn't spoken to Jean since his brother married her three decades ago.
