US Magazine claims 'multiple sources' have been telling them that Reese is around 12 weeks pregnant with her first child with new husband Jim Toth, but that the couple have no plans to make an immediate announcement.
Pics of Reese, 36, sporting a minuscule 'baby bump' have also been doing the rounds - although at 12 weeks that bump could just as easily be the result of a pasta dinner rather than baby!
The This Means War star is already mummy to Ava, 12, and Deacon, 8, her two children by ex-husband Ryan Phillippe.
Oooh, exciting! We hope it's true and another bump to add to the 2012 celeb baby list!
