This is as equally unexpected as it is AH-mazing news!
While we will welcome this collaboration into our ear holes with open arms, it's a little surprising. The 35-year-old actress once called the music recording process "the most challenging, horrifying experience of [her] life."
So after popping out another beautiful baby boy and whipping her body back into shape in record time, she must be running out of challenges. Ha!
Can't wait to hear your singing voice again, gurl!
We're sure it has only improved from that one time you used it to win an Oscar.
