Gwen Stefani and her husband Gavin Rossdale went sightseeing in Saint Paul de Vence, France with Bono and his wife Ali Hewson. They were also joined by Helena Christensen and her boyfriend Interpol star Paul Banks. Gwen wore a black maxi dress with a gaping side that revealed her bra. She accessorized with a black and white bag, flip flops, and cream vintage Triwa Henry square sunglasses. The group visited the modern art museum Fondation Maeght and spent time wandering around the exhibition. They were seen chatting and taking photos while enjoying their cultural day out together.
