Michelle Obama dances with 14000 kids during birthday tour of 'Lets Move'

London, Feb 10 (ANI): Michelle Obama got a crowd of 14,000 to dance with her to mark the second anniversary of her campaign to fight childhood obesity in the US on Thursday.

The University of Northern Iowa Interlude Dance routine has become a YouTube sensation, and the First Lady was more than happy to back her claim that she is ''pretty much willing to make a complete fool out of [her]self to get our kids moving'', as she told a keynote audience last November, the Daily Mail reported.

Joined by Rob Harper of Biggest Loser and sports stars including ice-skater Michelle Kwan, gymnast Shawn Johnson and WNBA player Tamika Catchings at the Wells Fargo Arena, she waved her arms in the air, swung her hips and showed the blaring youngsters how to perform the simple dance.

Speaking to the packed house, the First Lady told children, celebrities and state officials: ''This is so cool!... Happy birthday, Let's Move!'

Her enthusiasm did not just end there.

''I'm proud that you guys are eating your fruits and vegetables, I'm proud that you guys are walking to school instead of taking the bus," she said.

Performances by the Isiserettes and American Idol contestant Katelyn Epperly kept the mood cheerful even after a workout routine led by Harper. (ANI)
