MICHELLE OBAMA DOES 10 @ 10 WITH LENO!

Michelle Obama went 10 rounds on "The Jay Leno Show" Friday night, but the First Lady reserved all her punches for President Obama - and her own mom.
Appearing on "10 @ 10" - a comedy bit during which Leno asks 10 rapid-fire questions - the First Lady was asked to name the President's most annoying habit.

"Ohhh - we don't have enough time," Obama said before riffing on her hubby's Mr. Cool image. "He has no annoying habits. Right, Jay? None. He's perfect," before allowing that his ability to beat her at tennis was a problem.

As for First Grandma Marian Robinson, 72, she took a hit when Leno asked Michelle Obama who disciplined daughters Sasha, 8, and Malia, 11, the most.

"I can tell you who disciplines them the least, and that would be Grandma. She is worthless!" Obama said of her mom. "Cookies, TV, whatever they want."

The First Lady - who also urged viewers to support military families - played the protector when asked what the girls' Halloween costumes would be. "That's top secret," she joked.
