Stella McCartney co-chaired the NSPCC Pop Art Ball, held at the Banqueting House in London yesterday, and welcomed friends Naomi Watts and Rashida Jones to the arts-themed event (all three wore McCartney designs). The evening raised more than $1.7 million for NSPCC Rebuilding Childhoods Appeal, which helps fund therapy for children who have suffered abuse.
