HOLLYWOOD - Chris Martin is desperate to expand his brood of children with Gwyneth Paltrow by adopting a child.

The couple already has two young children--Apple and Moses--but they're not content to stop there.

And the Coldplay star is desperate to follow in the footsteps of other A-list adoptive parents, including Angelina Jolie and Brad Pitt, Meg Ryan, and Madonna and Guy Ritchie.

Paltrow says, "Maybe in four years I'll have two (babies) in a row, really quick again.

"But at that point, with Apple and Moses both potty-trained and sleeping through the night, would I really go back?

"My husband really wants to adopt, though. So I don't know, I'm sort of open for anything."
