Kelly Osbourne & Lourdes Leon Party Like Material Girls in New York (PHOTOS)

'Material' Launch
Kelly O steps out at premiere of 'Girl' line.
Madonna’s daughter Lourdes Leon pulled out all the stops for a fashionable night out to celebrate the 1st birthday of she and her mum’s Material Girl line at Macy’s Herald Square. Although Madge was absent from the event, she left the celebrations in the hands of her daughter, 14, and Kelly Osbourne, 26, who serves as the line’s spokes model.

The event turned into a full on runway show, as models hit the pink catwalk in the Material Girl clothing. Kelly and Lourdes giggled like BFFs from the sidelines, eventually strutting down the runway. Kelly sported a leopard print top, leather jacket and skirt, while Lourdes wore a flirty, yellow and white mini dress and black pumps.

Fans gathered on the fourth floor of Macy’s in NYC, to catch a glimpse of the twosome. Adding even more frills to the b-day bash, there was a four-tiered birthday cake decorated with sparklers and ribbons that was brought onstage. The Material Girl line launched last year, and Kelly took over the spokes model job in February, replacing Gossip Girl wild child Taylor Momsen.

There’s no denying that Madonna‘s little girl is all grown up! The 14-year old mini-mogul, who also launched a beauty product collection for Material Girl, is still making plenty of time for fun though. Just a few weeks ago, Lourdes hit the beach in Antibes, France, with some of her friends to enjoy some gun in the sun. The group were later spotted riding jet skis.
