Boxers or briefs? Michelle Obama reveals the answer

Does this mean POTUS goes commando like — Christina Aguilera?

You knew it was coming — the now-de rigueur "boxers-or-briefs" presidential election query. Only this time the target was the underpants owner's spouse, Michelle Obama — as in, which skivvies style does she prefer the commander in chief wear?

And when Live! with Kelly & Michael's Michael Strahan cringed through the question on today's show (in an interview taped Wednesday), Mrs. O was her unflappable and, um, cheeky self. Her answer, after a beat? "None of the above!" Four years ago, incidentally, her husband told Us Weekly, "I don't answer those humiliating questions. But whichever one it is, I look good in 'em!"

(In related celebrity knickers news, Aguilera said Thursday night on Chelsea Lately that she regularly doffs her drawers: "I like to be as free as possible at all times. It's just who I am," adding, "It's empowering.")

Mrs. O also revealed a perk of being FLOTUS — an empty purse. "I get teased for having a purse with nothing in it… No money, no keys… I have to find stuff to put in my purse."
