The pop superstars have both been made into one-of-a-kind dolls that will be auctioned off for the charity Project Angel Food via charitybuzz.com/auctions/barbie, with bidding starting at $1,000.
The Katy doll, made by Mattel designer Amy Lee, was inspired by the I Kissed A Girl’s cupcake dress, and also features hand-painted tattoos, sparkling pink shoes and glittered candy cane mic.
Nicki’s doll, meanwhile, sees designer Stephen Sumner making a beautiful replica of the frothy dress from her Pink Friday album, with plenty of bling.
The auction ends on December 19.
