It's kind of yesterday's news, but heard this morning that Michelle Obama is continuing to follow the star-spangled celebrity side of being America's First Lady and is going to appear in a cooking reality TV show.

Yup, Michelle is scheduled to make a guest appearance on the popular series 'Iron Chef America' which also features culinary glamourpuss, Nigella Lawson as a judge. Michelle agreed to take part in the show to promote her campaign of healthy living. During the show, which attracts an audience of 1.5m in the US, she will be seen talking to the chefs about the importance of getting children to eat vegetables.

So what's on the menu? I couldn't find anything on what Michelle will be dishing up, but one thing's for certain - it's going to be healthy.

Plus, Michelle is also quite the Good Life's Felicity Kendal, as many of the ingredients for the meals prepared in the show were chosen from the recently planted White House vegetable garden. Not sure if she'll be sporting dungarees and Wellies though?

And Michelle is obviously taking this TV appearance seriously, so much so she's done a dry run on Sesame Street - to celebrate its 40^th anniversary episode.

Definitely good practice for a celebrity cooking show, kids and bunch of puppet vegetables might be good training, Nigella excluded of course...she's delicious.
