When Katy Perry said "I do" to Russell Brand Saturday in northern India, she wore an Elie Saab haute couture dress, has learned.

A source tells Us the gown was dove gray and had lace sleeves.

Us previously reported that Perry, who turns 26 Monday, planned to have a rotating bridal wardrobe from designers Zuhair Murad and Donna Mizani for the private and spiritual ceremony, which was attended by 80 or so of the couples' closest family and friends and was performed by a Christian minister.

Hours after the wedding, a rep for Perry told Us the singer and her husband "are overjoyed to confirm that they were pronounced Mr. and Mrs. Brand."
