Casey Kasem's kids are seeking to free him from his wife, so to speak.
They are filing for a court's help to gain access to their ailing 81-year-old father, whom they haven't been allowed to see in three months, they claim.
In papers filed in Los Angeles Superior Court on Monday, his daughter Julie Kasem, 38, is requesting a conservatorship over her father's healthcare.
The children from Kasem's first marriage, Julie; Kerri, 41; and Mike, 40; allege that their stepmom, Jean Kasem, 59, has abruptly blocked all access to their dad.
The iconic American Top 40 host has been married to Jean for 30 years.
"When he was healthy, our dad used to talk to us all the time," Kerri said.
"We're his joy. Now we've been cut off from him. The same goes for many of his friends. We all just want to know that our dad is okay."
Jean Kasem and her lawyer have not commented on the allegations.
The kids, and more than a dozen longtime friends, staged a protest outside his L.A. mansion on October 1, demanding access to Kasem, to no avail.
Kasem, who has advanced Parkinson's disease, can't walk unassisted and began having trouble speaking about three years ago, his kids say.
Relations with their stepmom have been estranged their whole lives.
They insist that the feud has nothing to do with money because they're all "self-sufficient and are not listed in his will anyway," Kerri previously said.
