Madonna throws pre-prom party for daughter

Madonna helped her teen daughter Lourdes celebrate the end of her high school career with a pre-prom party on Saturday (21Jun14).

The Material Girl hitmaker organized a garden party in New York City for the 17 year old and her friends prior to their school's annual dance.

In photos posted on Instagram.com, Lourdes posed in a black and white polka dot dress next to her pals. A caption accompanying the image reads: "Pre prom turn up ! #yaaaaaassssssb**ch (sic)", while another shot shows off one of Lourdes' male classmates modeling his tuxedo, to which the Vogue singer added, "Strike a pose!"

The music icon took a break from serving as hostess and snapped a picture of a wine glass placed perfectly between her feet while she relaxed on the grass, and wrote, "Mama takes a rest! #graduateb**ch (sic)".

Lourdes is set to graduate from the Fiorello H. LaGuardia High School of Music & Art and Performing Arts on Wednesday (25Jun14).
