First lady Michelle Obama appeared on The Tonight Show with Jay Leno last night, revealing a few facts we may not have already known about her, the president, and life in the White House.

Although she was scheduled to discuss her upcoming book, American Grown: The Story of the White House Kitchen Garden and Gardens Across America, which is due out in May, she and Leno talked more casually about events in her everyday life, such as her recent birthday, President Obama’s singing debut, and the craziness that comes along with campaigning for the new election.

Leno started off by wishing the first lady a happy belated birthday (she celebrated her 48th on Jan. 17) and asking Mrs. Obama about the alleged cake that was made especially for her by her daughters, Sasha and Malia, and her mother. “This is unique in the White House because you don’t get to bake much. Last year [my mother] made a cake, and it fell. She wasn’t used to the oven. So she and Sasha and Malia baked my favorite cake, which is red velvet.”

Viewers also learned that despite her love of vegetables, the first lady absolutely hates beets. She does, however, boast that she’s in “better shape” than her husband. “We work out pretty much every day and we’re competitive.” One area where she admittedly can’t compete? “He sings to me all the time, and he has a beautiful singing voice,” Michelle said, when Leno asked about President Obama crooning a few lines of “Let’s Stay Together” during a fundraiser recently at the Apollo Theater.

Mrs. Obama also talked about how surprised she is with how easily the children have transitioned into life at the White House. “The girls are doing really well, I was really worried about whether they could have normal lives. They have a regular life, they’ve got friends, and they have sleepovers. Malia has a cell phone, and the girls get to earn one hour of television time per weekday if they’ve done all their homework.”

Before coming to the White House, Michelle cites the Obama’s hectic family schedule as being the primary cause for their own poor diet choices. “Like any family, we were busy, juggling schedules, eating out too much. We just made a few adjustments: cutting out sugary drinks, adding water, eating more fruits and veggies, and we saw significant changes.” Along with her new book, the first lady was also promoting “Let’s Move!”, which is an initiative that launched in 2010 in order to “raise a healthier generation of kids.”
