Where's the material, girl?

Madonna expressed herself at the Vanity Fair Oscars Party Feb. 27 by strutting the red carpet accompanied by her teenage daughter, Lourdes "Lola" Leon, in a skintight leotard that exposed her buttocks' cheeks.

The lithe, 52-year-old music icon wore a frilly lace negligee gown and black fur vest over a satiny leotard that ran a little high and tight, letting some of her famously taut rear assets show through her fishnet stockings.

The pop superstar and co-designer of Macy's "Material Girl" line wore her blond hair sleek and blown out and was dripping in Neil Lane jewels and a Solange Azagury-Partridge diamond Tree of Life bracelet.

Her 15-year-old daughter and design collaborator was actually more covered up in a shimmering, patterned sheath minidress accessorized by what one fashion commentator described as an "embarrassed look."

If Lola was a little uncomfortable with her famous mom's getup, who can blame her? Madonna, who has has said her oldest child isn't allowed to dye her hair or date until she's older, seemed to have lost the page on age-appropriate mom attire in her parenting guide.

Meanwhile, the duo agree on one lucky star: Kelly Osbourne was their mutual choice to be the new spokesmodel for their fashion brand.
