We hear that Madonna will eschew some of her Dolce + Gabbana costumes on her tour for those by Ricardo Tisci, the head designer at Givenchy. Madge will wear some ready-to-wear pieces by the French house helmed by the Italian designer, and also some of their recent couture collection. The singer has already been spotted out and about in heaps of Givenchy clothes - here she is in People Magazine, getting called out on her severely chic ensemble. Another link to the label made famous by Breakfast at Tiffany's? Justin Timberlake is the new face of Givenchy's men's perfume and the latest pop star to collaborate with Madonna on a hit song.
