During her most recent appearance on The Ellen Show, our First Lady threw it back, showing off her prom pic from many moons ago. â€œThat split was a little high,” she said of the leggy photo. “I donâ€™t know if Iâ€™d let my kids go out with a split that high, so letâ€™s not show this to Malia and Sasha.” I’m sure they’ve already seen it! LOL! Check out the throwback pic below.
