“Rob and Chyna have split for good, and now Rob wants full custody of Dream,” an insider tells In Touch exclusively. “Kris [Jenner] is 100 percent behind him. She doesn’t want him paying child support.”

And it would appear that Rob may very well get his way; according to the insider, Chyna has a “mystery man” helping her with her significant debt — but she’s scared that her financial vulnerability could make it easy for Rob to win full custody of her little girl.

“Chyna has already spent over $290,000 and is in debt,” the insider says. “She fears she will lose everything, including Dream, to the Kardashians.”
