Here is an update from TMZ: UPDATE
: We just pulled legal documents regarding custody of Debbie and Michael's kids, and you can see here
the moment when Debbie gave up her parental rights.
In the docs, when Debbie is informed she'll have no rights, she says, "Not that I don't love them. I do. I think they're adorable. They're his kids. They're his kids. They're not my kids. They're his kids."
