 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."

 First lady Michelle Obama cajoled Jay Leno into nibbling on apples, sweet potato fries and a pizza made with eggplant, green peppers and zucchini on the "Tonight Show," breaking his long-held aversion for all-things-healthy in his diet. 
 
 Leno once told a magazine he hadn't eaten a vegetable since 1969, and he insisted he tasted his last apple in 1984. That didn't dissuade the first lady, who's promoting her "Let's Move!" campaign to get kids excited about fitness and healthy eating habits. 
 
 Earlier, Obama poked at him in a Twitter post, hinting she'd "get Jay to eat some veggies" on the NBC show. 
 
 He did. 
 
 "That does smell very good. I assume this is sausage-pepperoni," the comedian quipped as he eyed the pizza made with a whole-wheat crust. 
 
 She convinced Leno to dip an apple in honey made from beehives in the White House garden: "It will help it go down easier," she assured him. 
 
 "White House honey? That sounds bad," Leno told her. "You know, with a different president that could mean a whole different thing, `a little White House honey.'" 
 
 The first lady is on a two-day swing through California where she'll promote her initiative while attending two events to help Democrats raise money for the upcoming elections. 
 
 She told Leno she's not doing anything special to prepare for what's expected to be a tough re-election campaign for her husband, President Barack Obama. 
 
 "You know, there's really no way to mentally prepare for it. You take each day as it comes," she said. 
 
 Republican Mitt Romney has been ridiculing the White House and might face the president in November, but the first lady graded the former Massachusetts governor's singing voice with something like a sly endorsement. Romney surprised supporters in Florida with an on-pitch version of "America the Beautiful" on Monday, and Leno asked the first lady for her opinion. 
 
 "It's beautiful," she said after a pregnant pause, with a laugh and raised eyebrows. "And it is America's song, and it's a song that's meant to be sung by every American," the first lady said in a taped appearance for the NBC show. 
 
 Leno told her, "That is right, regardless of political affiliation." 
 
 But she swooned over her husband's singing _ Obama took a brief turn as a soul singer earlier this month at a New York fundraiser, crooning a bar from an Al Green classic. She says he does a little Marvin Gaye, too. 
 
 "He does have a beautiful voice, and he sings to me all the time," she told Leno.
– If you thought the recent clip of President Obama singing was a fluke, think again: "He does have a beautiful voice, and he sings to me all the time," Michelle Obama told Jay Leno last night. Her husband often sings that very same song (Al Green's "Let's Stay Together"), she said, adding, "He sings a lot of Al Green, Marvin Gaye, a little Stevie [Wonder]. He likes the classics." As for Mitt Romney's rendition of "America the Beautiful"? A diplomatic first lady said, "It's ... a beautiful song. It is America's song. And it's a song that's meant to be sung by every American." Obama, who is in California to promote her Let's Move healthy eating campaign, also convinced Leno to eat some nutritious food including apples, honey, and some veggies. Leno once told a magazine that 1969 was the last time he ate a vegetable, the AP notes. Click through to the Huffington Post for another clip from the interview.
