The first lady said if she had the musical talent Beyonce has, she would absolutely want to be "some great singer" in another life. 

Instead, the first lady has written a book — her first — titled "American Grown: The story of the White House kitchen garden and gardens across America." She will promote the book next week with a media tour that includes appearances on Jon Stewart's "The Daily Show," ABC's "Good Morning America" and "The View" on Tuesday, the day of release.

Obama is widely known for her anti-obesity initiative Let's Move!, advocating organic foods and for challenging talk-show hosts to push-up competitions. She told the magazine she and President Obama no longer compete when it comes to physical fitness. "Not anymore, because I’m in way better shape than he is,” she said. "We don't take ourselves too seriously. At the gym, we're spending a lot more time laughing about who is trying to get out of doing their push-ups, who's whining too much.'

“That’s been my one goal: I don’t want to be caught dead in a bathing suit!”
