According to Star Magazine, the singing star and the Hollywood socialiate have bonded through frequent posts on CafeMom.com, a parenting website where mommies and mommies-to-be share advice on raising their tykes.

Ash and Nicole are both regular visitors.

“They were writing to each other right up till Ashlee went into labor.”
