Kasem family feud: Jean Kasem's acting past includes popular role on 'Cheers'

Radio icon Casey Kasem's three children have accused their stepmom, Kasem's wife Jean, of not allowing them to see or speak to their ill father for over three months.

So far, Jean Kasem has remained silent, but the feud has many remembering the one-time actress' short stint in the spotlight.

Jean Kasem burst on the scene as actress Jean Thompson playing Loretta Tortelli on popular sitcom “Cheers.” Loretta, the ditsy blonde wife of Carla's ex, Nick Tortelli (Dan Hedaya), appeared on the show from 1984 to 1993 and even scored her own spin-off, “The Tortellis,” which had a 13 episode run in 1987.

Jean, has been married to Casey, who is 31 years her senior, since 1980, and has one child of her own with him, but her estranged stepdaughter, Kerri Kasem, claims it hasn’t exactly been 33 years of wedded bliss.

“He would say she's a very insecure woman, she does things I don't like, but I'm married to her. I gave her my promise,” Kerri told FOX411. “My Dad has such amazing integrity. Too much so, that he got involved with someone, instead of saying, 'Hey this was a terrible mistake,' he kept his pain private.”

Jean had other television roles throughout their marriage, including stints on “Growing Pains,” “Johnny Bravo,” “Hope & Gloria” and “Good vs Evil,” and acted in a slew of TV movies. Most of her roles were minor (for example, she played the part of “tall woman at party” in 1984 film “Ghostbusters”), but Kerri says she was too busy to bond with her husband's kids.

“Jean has never, once in the 30 years called us up and said, 'Let's hang out, let's do something.' It just doesn't happen,” Kerri said. “She's never wanted a relationship with any of us.”

Kerri added that she and her siblings were not invited to their father’s wedding, and were not allowed to talk to their half-sister, Jean’s daughter, Liberty.

“I don't want it to be step-kids hate step-mom, step-mom hates step-kids and we're fighting,” she said. “It's funny, we're not even fighting. If we were fighting we'd be communicating. There is no communication.”
