During the Academy Awards ceremony, Chris made a joke about Jada Pinkett Smith's hair loss before he presented the Best Documentary Feature award.
While Will laughed at the joke at first, Jada, who suffers from alopecia, appeared visibly unimpressed and Will responded by getting on stage and smacking Chris before warning him to never speak about her again.
When asked for her reaction at the Governors Ball on Sunday, Tiffany said she thought it was "beautiful" how Will stood up for his wife, her Girls Trip co-star Jada.
