Family matters.

What do Tori Spelling and Kevin Federline have in common? The Dr. Keith Ablow Show, apparently. A week after Tori’s ex-husband Charlie Shanian appeared on the program, Shar Jackson, the mother of Kevin’s first two children, will have her own sit-down with the self-help doctor, says MSNBC’s Scoop (http://msnbc.msn.com/id/14626187/). On Thursday’s show, Shar will reveal that she wasn’t sad when K-Fed left her bed, but that writing off his kids was a whole other story.

"As far as I was concerned, I was ok that the relationship ended…but the family breaking up is something painful," Shar tells Dr. Ablow. "And honestly I didn’t let it happen. Now in the beginning it was rough, because he was overseas, so I really didn’t have much control over there. But when he came back home, I told him ‘Kevin, I’m not going to let you be a convenient father, when it’s convenient for you. If you are going to be part of these kids’ lives, then you’re going to be a part. If not, then you’re not.’"

Shar also maintains that she considers Kevin’s current wife, Britney Spears, a member of her children’s "extended family," but that she has yet to meet Kevin’s kids with her. Could be Toxic, you know.
