EXCLUSIVE: Martha Stewart is bringing out the big guns for a big Mother's Day special on the Hallmark Channel, with an appearance from First Lady Michelle Obama! "I'd been dying to meet her," the domestic diva told me on the set of 'The Martha Stewart Show' this week.

Joining the First Lady will be the Second Lady, Dr. Jill Biden. So many powerful women in one place! "I don't think any of us were nervous," Martha told me. "We are all professionals."
