Six-time Grammy winner Toni Braxton, 32, and Mint Condition keyboardist Keri Lewis, 28, were married in a private outdoor ceremony on a 60-acre estate near Atlanta on Saturday, reports the Associated Press. Former Atlanta Mayor Andrew Young officiated. The guest list, some 250-strong, included current Atlanta Mayor Bill Campbell, singer Monica, rapper Mack 10, and LaFace Records label stars Usher Raymond, Donell Jones, Tionne "T-Boz" Watkins and Rozonda "Chilli" Thomas. A 16-piece orchestra played Bach and hip-hop. The R&B singer met Lewis four years ago when his Minneapolis-based band accompanied her on tour. Vera Wang designed Braxton's bridal gown, which was of ivory satin with a notched and beaded bodice, and a beaded train with matching veil. Stephen Russell designed her diamond-crusted gems.
