Michelle Obama 'Tonight Show' Appearance: First Lady Says President 'Sings To Me All The Time' (VIDEO)

On Tuesday night's "The Tonight Show with Jay Leno," Michelle Obama explained to the world that her marriage includes a musical element.

Referring to President Obama's now-famous rendition of Al Green's "Let's Stay Together," Leno asked the First Lady, "Did you ever think at this point in your lives together he [President Obama] would become a singing sensation? Did you ever think that would happen?" She responded, "No. No. Not at all. Not at all."

Obama explained to Leno that the President's performance at Harlem's Apollo Theater was "completely spontaneous" and that she "didn't even hear about it until it got on YouTube." She told the late-night host that her husband "does have a beautiful voice, and he sings to me all the time."

When pressed about what types of music the Commander-In-Chief enjoys belting out, Obama said, "He sings a lot of Al Green, Marvin Gaye, a little Stevie [Wonder]. He likes the classics."

Naturally, Leno brought up GOP presidential candidate Mitt Romney's recent vocal performance of "America The Beautiful." When Leno asked if the First Lady had seen the clip and what she thought of it, she answered, "I saw it in the green room." With a tongue-in-cheek tone, she continued, "It's...a beautiful song." Steering clear of partisanship, she explained, "it is America's song. And it's a song that's meant to be sung by every American."

Per the Associated Press, the First Lady is currently "on a two-day swing through California where she'll promote her 'Let's Move!' campaign promoting fitness and healthy eating for kids, while helping Democrats raise money at two events for the upcoming elections." Running with the theme of healthy eating, Obama brought Leno a series of nutritious snacks, including apples and honey.

During the appearance, Leno asked Obama how she prepares for what is sure to be an intense general election campaign. "You know, there's really no way to prepare for it," said the First Lady. She elaborated, "You just take each day as it comes. I think Barack and I, our motto is, we try to do the best job that we can do every single day. And the hope is that that will speak for itself."
