Gladys Knight & William McDowell, Together For 19 years

While there are many soul singers out there, there is only one empress for the whole genre: Gladys Knight. With hits like Midnight Train to Georgia and That’s What Friends Are For, you’ll understand why she has was given that nickname in the first place.

She has been married four times in her life. However, it seems like the fourth time’s a charm for her as she and gospel singer William McDowell, her fourth husband, have been married since 2001. That’s her longest marriage out of the four, which is quite amazing considering the 32-year age gap between them. They have 17 grandchildren and ten great-grandchildren.
