Serena Williams to reportedly appear on Kai Cenat's Mafiathon 2 stream as part of McDonald's campaign

Twitch streamer Kai Cenat is hosting his most successful streaming event yet — the second edition of his infamous subathon series, Mafiathon. As is typical of the format, Kai streams around the clock, even sleeping and showering live. However, what sets this event apart are the guest appearances, considering that most of Cenat's broadcasts have included celebrities from different backgrounds.

The streamer incorporates a mixed bag of guest appearances, from hip-hop artists like Lil Uzi Vert and Kodak Black to television stars like the cast of Disney's Good Luck Charlie. On November 11, 2024, reports of a collaboration between Kai Cenat and tennis legend Serena Williams flooded the internet.

The two will host a special live stream at 5:30 p.m. ET on Kai's Twitch channel, marking an unprecedented crossover between the worlds of streaming and professional tennis.

Kai Cenat and Serena Williams: Details explored

Kai and Serena will be collaborating in a stream titled The Not Not A Big Mac Stream, which references the streamer's collaboration with McDonald's that happened early in October 2024. The premise of this crossover was to announce a limited-time offer including a Chicken Big Mac, with Kai acting as an ambassador for the launch.

Kai's streams are all over the place, including skits, challenges, pranks, and much more. Considering his antics, it wouldn't be surprising if the two got on the court together to play a game of tennis.

Kai Cenat and Serena Williams share some common ground as well, considering both are sponsored by Nike. In September 2024, Nike released its first-ever pre-order sneaker dubbed "Low Poly", with Kai as the launch's mascot.

Although she retired in 2022, Williams remains an American tennis icon and has won 23 Grand Slam singles titles. She is a celebrated figure in the sport and still occasionally appears in exhibition matches. Outside the court, she continues to engage in ventures beyond the sport, such as her work with Serena Ventures and involvement in various social causes.

Over the years, Kai's streams have consistently included some elements of sport. His partnership with college football star Travis Hunter has garnered particular attention. The two have appeared in streams together that highlight their chemistry and drive viral social media moments, including Travis adopting some of Kai’s humorous celebrations on the field.
