Gwyneth Paltrow may already have her hands full with a couple of little ones—Apple, 4, and Moses, 2. But the Iron Man star hasn't ruled out the possibility of adding to her and Coldplay hubby Chris Martin's brood.

"I may force myself to do it one more time, because the result is so worth it," the Oscar winner reveals in the July issue of Harper's Bazaar, despite the fact that during both her pregnancies she "wanted to throw up all the time."

Of course, there's always adoption, which the 35-year-old actress admits to being "very open to...we're so fortunate, and we kind of owe it to humanity."

Especially if it means not having to bow down to the porcelain god.

But don't expect motherhood to completely replace making movies. "One of the things that I realized when I took so much time off is that you're not just an artist because you fall into the job. It's something within you, something that burns. It's not a hobby, it's a need."
