Bre Tiesi finally addressed Nick Cannon's ex-wife, Mariah Carey, during season 9 of Selling Sunset. While catching newcomer Sandra Vergara up on the office drama in the newest batch of episodes, which are currently streaming, Bre, 34, mentioned that her feud with Chelsea Lazkani started over Nick, 45. "Doesn't he have, like, 20 kids?" Sandra, 37, asked Bre, who clarified that Nick has 12 children. Sandra followed that up by referring to Cannon as "Mariah Carey's ex" before asking whether Bre ever "met" the singer, 56.
