The actress, 46, simultaneously revealed that she had not been on speaking terms with Union, 45, for 17 years and that they had recently reconciled.
“I have a really touching episode with Gabrielle Union,” she said. “We haven’t been on the best of terms for 17 years and we have a reconciliation.”
“When the producers said we want to do a girlfriends show, her name just kept coming up,” she continued. “It just couldn’t be anything else.”
While the Girls Trip star may now be on good terms with the Being Mary Jane actress, she’ll be the first to admit she has no clue as to how their disagreement began.
“We don’t even know how it started!” she said, adding their feud was “definitely” over.

“Red Table Talk is about raw truth, love and deep passion. My mother is old school, Willow is new school, and I find myself right in the middle,” Pinkett Smith told PEOPLE in April. “I’ve done a lot of sharing and growing on Facebook. Being able to engage with the Facebook Watch community in such a deeply personal way is amazing, and I’m excited to be part of something new.”
“As a 17-year-old, it’s important for me to be able to talk openly about what’s going on in my life…there have been too many times I have felt alone,” Willow said.
