Michelle Obama teases Gabby Douglas over fast food

(AP) Michelle Obama is teasing Olympic champion Gabby Douglas about eating fast food to celebrate her achievements.

The first lady, an advocate of healthy eating, and Douglas taped an appearance together Monday for NBC's "Tonight Show" with Jay Leno.

When Douglas was asked how she marked her stellar Olympic showing, the 16-year-old gymnast said she "splurged" on a McDonalds' sandwich.

Mrs. Obama responded, "You're setting me back, Gabby," which drew a "Sorry!" from the athlete.

According to a partial NBC transcript, Mrs. Obama also used her "Tonight" appearance to praise her husband's healthcare overhaul law.

During the just-ended London Olympics, Douglas became the third straight U.S. athlete and first African-American to win the all-around title. She and her teammates gave the U.S. its first Olympic title in women's gymnastics since 1996.
