Madonna has become a real-life material girl. The hit music star has teamed up with H&M clothing to release a line of her very own. The new line, which is expected to hit stores in March, is called M by Madonna and is an exclusive line made by the diva herself - in collaboration with H&M's head of design, Margareta van de Bosch.

Madonna is following in the footsteps of other highly known designers working in collaboration with H&M to release their own clothing lines. Stella McCartney, Karl Lagerfeld and Vicor & Rolf are also among the team who make up this amazing company.

A spokesperson for H&M insists that Madonna had creative control over the line and that she took part in even the smallest details associated with the new collection. The 48 year old music icon is excited for the new line to release and has been promoting the designs during her "Confessions" world tour.
