Serena and Venus Williams joked with their sisters about mom's unpredictable wit in first-ever interview as a family

• Will Smith hosted Venus and Serena Williams as well as their mom and sisters on "Red Table Talk."
• The appearance was the family's first-ever interview as a full family.

Venus and Serena Williams have done more than their fair share of interviews over the course of their illustrious, decades-long professional tennis careers.

But for the first time ever, the superstar sisters — who own a combined 33 Grand Slam singles titles between them — were joined by their mother and two sisters for an unprecedented full-family sit-down conversation with Will Smith.

The quartet — Venus and Serena, older half-sisters Isha and Lyndrea Price, and mom Oracene Price — will be on this week's episode of Facebook Watch's "Red Table Talk," which begins streaming Wednesday at 3 p.m. ET.

With Smith guiding the conversation, the women reminisced about the past, discussed their dynamic as a family, and reflected on the process of creating "King Richard" — a blockbuster film about the Williams sisters' journey to tennis glory spearheaded by their father, Richard. Smith plays the titular character in the movie, which comes out in theaters and on HBO Friday.

In a particularly funny moment from the episode, the sisters joke about their mom's witty sense of humor that can, sometimes, become a bit unpredictable. Venus stresses that Oracene is "so fun" before Serena interjects that "we do hold our breath a lot sometimes when she speaks in public."

"I think that's why she ended her Twitter account — or she was forced to," she added as the whole group laughed.
