Looks like Lourdes Leon is following along quite nicely in the footsteps of her uber-talented mom, Madonna!
First the mother/ daughter duo aligned their passions for fashion with the 2010 Material Girl collection line for Macy's, but this time around, Lourdes is lending her voice to her mom's new album, MDNA.
A minute-long preview of the song Superstar hit the web today, and if you listen closely, Madge's talented offspring can be heard singing back-up vocals on the track.
MDNA will be released on March 26, but you can pre-order the deluxe version on iTunes now.
