Make a bid on Gwen Stefani's custom-designed Bugaboo Cameleon. All the proceeds are donated to help eliminate AIDS in Africa.

Gwen Stefani sure knows how to roll in style. The mom-of-two, rocker and creative director of L.A.M.B. has signed and designed two customized Bugaboo Cameleons. While Kingston and Zuma get to ride in one, the other is being auctioned off on starting today to celebrate World AIDS Day.

Not only does the stylish buggy feature a fun graffiti-style floral fabric from Stefani’s latest collection, the canopy and storage basket are lined with Vachetta leather trim and embellished with rounded pyramid studs. Want it? You have until Dec. 5 to make a bid. All of the proceeds will be donated to The Global Fund, which aims to help eliminate mother-to-child HIV transmission in Africa by 2015.

While there will only be one winner, anyone can support the cause by purchasing Bugaboo products year round. The company donates one percent of its annual sales to The Global Fund.
