Paltrow shows off a new look on the cover of W.

Gwyneth Paltrow is back.

She's splashed on the cover of September's W magazine, out nationwide Aug. 17, as she prepares for the October release of brother Jake's romantic comedy The Good Night, in which she plays the girlfriend of a washed-up pop star. The actress, 34, also has been busy filming the action thriller Iron Man with Robert Downey Jr.

The projects follow a break from major roles to spend time with husband and Coldplay frontman Chris Martin, 30, and their children, daughter Apple, 3, and son Moses, 1.

Does she see more kids in her future? "I have a dream version where I think, maybe in four years I'll have two in a row really quickly again — how fabulous to have a whole bunch of them! But then at that point, when everyone's potty-trained and sleeping through the night, are you really going to go back? … My husband really wants to adopt. So I don't know; I'm sort of open for anything."
