Looks like those Saltines did the trick!

Though she was spotted Monday in L.A. carrying a pack of the crackers on her way to lunch with fiance Will Kopelman, a pregnant Drew Barrymore must have been feeling well enough to hop a flight to Paris.

The Big Miracle star, 37, strolled hand-in-hand with her art consultant beau, 34, in the City of Lights Wednesday, where they headed to the Musee de L'Orangerie.

The actress' rep has not replied to requests for comment about her pregnancy, but a source tells Us Weekly Barrymore and Koppelman are thrilled to be welcoming their first child together.

"They have been trying to get pregnant," a Barrymore pal says. "That's why they got engaged...They are very happy! She's ready to settle down and be a mom."
