Waterloo, Iowa (CNN) - Going from a couch next to Jay Leno to the campaign bus with the president, first lady Michelle Obama will join the final leg of her husband's Iowa bus tour on Wednesday.
"This is where the journey began for him and where it began for the first lady, and Iowa will always have a special place in their hearts," said White House spokesman Jay Carney.

Earlier in the week Mrs. Obama made an appearance on NBC's "The Tonight Show with Jay Leno," where she dished about the Olympics, the "kiss cam" malfunction, and stumped for the president.
"Campaigning is a privilege" the first lady told the audience, before revealing her proudest moment of the president's first term.
"Health reform. I mean, you know...something that hasn't been accomplished by a sitting president in a century," she said.
The first lady remains a popular figure and the Obama campaign considers her a key asset.
There's "no better advocate for the president's policies than the first lady," said Jen Psaki campaign spokeswoman.
They're hoping her appeal will sell in Iowa, a key battleground state with only six electoral votes, but with immense political clout.
The first couple will appear jointly at the Alliant Energy Amphitheater in Dubuque. Then follow that rally with a final stop at the Village of East Davenport in Davenport.
Go FLOTUS – you are the BEST!!!!
The First Lady had better stay on-message.
We can't afford to have her digresss and scold IA farmers for the effects of pork fat and corn syrup on American obesity.
classy lady. She is an asset. Smart too. Forward 2012
Mrs Obama you are one the best First Ladies
Perfect pair ! She can shuck and jive while Barrack does the limbo !
This woman has done nothing but spend and act rich. i hope obama has a fleet of moving vans to get all her stuff she splurged on out of the white house come jan 2013. you wont be able to find a moving van in washington because obama will be using them all.
Get out of Iowa Obama and Michelle. You two care nothing for the citizens.
Way to go, Michelle! You and the President got my vote this November! OBAMA/BIDEN 2012 AND BEYOND!!!
Mrs. Obama is so cool. I can't imagine the country club wife allowing a wrestler (I think) pick her up or sound human and funny on the leno show.
Can you imagine this horse wife running around with the kids?
