Jackson, 31, has two children – Kori, 5, and Kaleb, 3 – with Federline, 29, and says that she watches Preston, 2, and Jayden James, 1, who are Federline's kids with Spears, 25.
"We definitely make sure the kids all bond together," Jackson told reporters Tuesday night at EA's Launch For The Need For Speed Game in L.A. "I mean, they're siblings, they need each other."
Jackson also stresses that she and Federline strive to keep their family closely knit, despite whatever differences she and he might have.
"We're not together or anything but we're definitely still a family unit," says Jackson, who perhaps remains best known professionally for her portrayal of Niecy on the 1996-2001 UPN show Moesha.
Best of Friends"Honestly," says Jackson, "we're like the best of friends. Obviously, the relationship didn't work out for a reason, and we're cool with that. But we're still a part of each other's lives. And our children get to see two people who aren't together but still have a great relationship, and I think that's really important."
Jackson, who in the past has repeatedly praised Federline's parenting skills, says she exclusively trusts him with her kids. "I know he's in a good place," she says, "the kids are in a good place, and I made sure from day one – I told him, 'You make sure you have our children.' "
And just how is K-Fed holding up in the fight with Britney over their kids? "He's great," says Jackson. "We don't even talk about that stuff, because that would be a non-stop conversation, and we don't even go there."
