No wonder Gwyneth Paltrow is a whiz in the kitchen. We're hearing her hubby Chris Martin asked Jamie Oliver to teach wife to cook. Jamie revealed that he knows Gwynny because Chris rang him and asked if he'd give her a cookery lesson for her birthday. Jamie is a big Coldplay fan so he said when he got the call it was a done deal. The pair spent the afternoon producing an amazing duck ragu which Gwyneth later included in her own 2010 cookbook, Â‘My Father's Daughter: Delicious, Easy Recipes Celebrating Family And Togetherness'. Now Gwynny is that not technically stealing Jamie's recipe! The stunning actress turns 40 at the end of the month.
