Benjamin "BeBe" Winans and Priscilla "CeCe" Winans are siblings in gospel's legendary Winans family. Another sibling in that family is Marvin L. Winans, Sr., who is also the pastor of Perfecting Church in Detroit, MI.
Vickie Winans (maiden: Bowman) is the ex-wife of Marvin L. Winans, Sr.
To that end, she is the "former" sister-in-law of BeBe & CeCe Winans. No bad blood, though, praise God!
