The caption from our friends at WENN identifies this photo as "Barry White and his wife at a Hilton Hotel, circa 1999." That would make this woman Glodean James White, whom Barry White married in 1974.
But according to Wikipedia, the couple "reportedly divorced in 1988, however, they were still legally married until White's death in 2003 although they lived separate lives." Glodean James was born in 1946, which would make her about 53 years old if this photo is from 1999. That age seems... possible, but not probable? We are doubtful.
