In an appearance on ‘The Dr. Keith Ablow Show’, Shar Jackson explains her pain of breaking up with Kevin Federline in the public eye. “My oldest daughter Cassie would come home from school in tears, everybody wanted to know, ‘Mommy why did Kevin do this? Why this? Why that? People were teasing me,’ That was the only part that just killed me,” Jackson confessed. Shar also talks about her relationship with K-Fed’s wife, Britney Spears. “She’s part of our extended family,” the jilted ex said. She does add, however, that she has not met their children. “I keep my distance,” she says.
