VIDEO : Jessica Simpson and Sister Ashlee Attend Diana Ross' Son Wedding

Diana Ross' eldest son, Ross Naess, is officially a married man! The 29-year-old said "I do" to Kimberly Ryan at Rancho Dos Pueblos in Goleta, California, on Saturday, in a gorgeous bohemian-themed ceremony. Kimberly, who is pregnant with their second child, wore a stunning white-and-gold Maria Korovilas gown and matching veil, while Ross donned a classic black Ralph Lauren tuxedo and top hat. Evan Ross and his wife, Ashlee Simpson, attended the ceremony, and both played major roles in Ross and Kimberly's special day. Also in attendance was Ashlee's older sister, Jessica Simpson, who put her own glam take on the bohemian theme.
