VIDEO : Michelle Obama Recruits Female Celebrities for Girl Power Song 'This Is for My Girls'

As she gears up for her appearance at SXSW, the First Lady has already begun recruiting the likes of Missy Elliott, Kelly Rowland and Kelly Clarkson for a girl-power song called "This Is For My Girls." Inspired by the First Lady's Girls Learn initiative, which aims to help "more than 62 million girls around the world" to stay in school, the track also features Zendaya, Janelle Monae, Jada Grace, and Chloe & Halle. The song dropped on radio on Tuesday, and will be available for purchase on iTunes at midnight. All proceeds will benefit the Peace Corps Let Girls Learn Fund.
