Jackson, who appeared in the sitcom "Moesha" and 2000 film "Love & Basketball," has two young children with Federline and said "he loves his kids to death."
Jackson said she is willing to let her kids have a relationship with Spears' child. "I mean, they're family, so if the other side of the family permits, then yeah," she said.
Jackson, who is starting a cosmetics line with a lip gloss called "He Cheated," has accused Federline of being unfaithful, but said she doesn't bear him any ill will.
"It's cool," she said. "Obviously, God didn't think that's who should be in my life at this particular moment in time and that's all right."
In July 2004, Spears has told People magazine she plans to meet Federline's children and would like children of her own someday.
"I definitely want to have some kids," she said. "I see myself with four or five."
