The beautiful woman in the photo, who prepared lunch for the First Lady is Nigella Lawson. She is a very popular TV chef, has authored a couple of cookbooks, writes a newspaper column, wife, mother... Not unlike Martha Stewart except she is kinda sassy and not as much a perfectionist ... also lots of men drool over this domestic goddess. LOL Some US cable companies carry her cooking show.
I saw her name on the info about the picture, but couldn't remember it, and didn't have time to go back and check it out. Thanks for filling us in, Darlin'!
