John Cena joins Kai Cenat live on stream in front of over 240,000 viewers

Kai Cenat and his stream have played host to some pretty big names over the years but today's collaboration might take the cake with WWE superstar and Hollywood actor John Cena stopping by.

The wrestler-turned-superstar slammed through Cenat's doors in front of nearly 250,000 live viewers as part of a McDonald's promotion. Alongside fellow streamer Fanum, Cenat and Cena spent the almost two-hour stream chatting and eating the new Chicken Big Mac.

Cenat appeared in a McDonald's ad for the burger just last week. The ad, which sees Cenat driving through a McDonald's and ordering a Chicken Big Mac while a choir sings about the "not NOT a Big Mac" — but the Oct. 13 crossover with Cena took it to the next level.

The stream was far from a surprise, with McDonald's revealing the epic crossover on Oct. 12. In classic John Cena fashion, the superstar burst into Cenat's room to his own theme song as the streamer cheered on. Prior to Cena's arrival, Cenat claimed the pair were "basically related" as his surname was one letter away from matching.

Cena immediately ripped into Cenat's messy carpet and its "patina" while the streamer's chat blew up with "Who is Kai talking to? There's nobody there!" as many referenced Cena's trademark "You can't see me" catchphrase.

After Fanum's arrival, the trio ate Chicken Big Macs while Cenat explained streaming vernacular and gifted subscriptions. Cena was drawn into reading Cenat's chat before Fanum grabbed matching Chicken Big Mac chains for the group. A few of Fanum's friends also rocked up dressed as McDonald's burgers.

Cena spent the rest of the stream answering questions about his career and giving advice to chatters before helping Cenat announce Mafiathon 2, a sequel to a month-long streaming run that saw the streamer rack up an incredible 46 million watch hours and break the all-time subscriber record at the time.

Cenat can now add Cena to the list of superstar guests on his "KaiCarly" show, with the streamer playing host to the likes of Nicki Minaj, Kevin Hart, and Ice Spice. More recently, Cenat ran his own NBA-style basketball draft following his addition to NBA 2K25.

Cenat didn't give a start date for Mafiathon 2, but he said that it would begin "when we see him next," so we imagine the subathon to be right around the corner. Stay tuned to esports.gg for the latest!
