We already know that Michelle Obama, the First Lady of the United States of America, will give a keynote address at SXSW tomorrow, and that she’ll be joined by some famous friends: Missy Elliott, Dianne Warren, and Queen Latifah. And now we know what that’s all about. Billboard reports that Obama has put together an all-star women’s-empowerment anthem called “This Is For My Girls,” and it’ll be out at midnight tonight.

The song is part of a couple of White House initiatives, Let Girls Learn and #62MillionGirls, and it’ll feature an impressive lineup of contributors: Missy Elliott, Janelle Monaé, Kelly Clarkson, Kelly Rowland, Zendaya, Chloe & Halle, Jadagrace, Lea Michele. And champion ballad-crafter Diane Warren wrote the song. You can hear a rip of the song here.
