BURBANK, Calif. (AP) - Michelle Obama is headed back to Jay Leno's stage.

NBC announced Monday that the first lady will make her third appearance on "The Tonight Show" on Aug. 13 to talk about the London Olympics and life with President Barack Obama and their children at the White House.

On her last stopover in January, the first lady promoted her "Let's Move!" campaign to get kids excited about fitness and healthy eating habits.

She managed to convince vegetable-hating Leno to nibble on apples, sweet potato fries and a pizza made with eggplant, green peppers and zucchini.

In London, she played a little tennis with kids, handed out some hugs and posed for photos with strapping athletes as she formally began her stint leading the U.S. Olympics delegation.
