Kim Kardashian’s stoic behavior while being showered with boos at the Netflix roast of Tom Brady made comedian Andrew Schulz wonder if she was even really there.

Schulz, 40, participated in the live skewering of the NFL legend, 46, which aired on May 5 from the Kia Forum in Los Angeles. Kardashian, 43, was also present, but Schulz claims the reality star seemed “dissociated” after receiving a less-than-warm welcome from the crowd. On the latest episode of his podcast “Flagrant,” Schulz speculated whether Kardashian had been replaced by a “robot where she can essentially control what it says, but there’s no human aspect to it.” He observed, “She sat with perfect posture for three hours straight. Smiled, laughed. I’ve never seen anything like that. Completely unaffected.”

When Kardashian took the stage to perform a brief set mainly focused on the dating rumors surrounding her and Brady last year, her demeanor remained unchanged. “Even when she was up there, they were kind of booing her,” Schulz said. “It didn’t make her smile. It didn’t make her sad. It was nothing.”

Despite Kardashian’s lack of reaction, the booing was cut out of the edited version of the roast.

Schulz compared the crowd at the event to “a Buffalo Bills tailgate,” indicating the rowdiness of the atmosphere. One man, in particular, made sure Kardashian knew exactly how he felt. “Kim’s up there doing her set, and then this guy in the stands, out of nowhere, just goes, ‘Bitch!’” Schulz explained. “It was as if he had been holding it in for a whole minute and he just couldn’t hold it anymore.” He added, “Just seeing Kim Kardashian on stage for three minutes was too much for him to hold it in.”

After the roast, a source exclusively told Us Weekly that Kardashian was “unfazed” by the negative reaction. The insider further explained that she had a “blast” and, despite the harsh reception, “wouldn’t change a thing.”

“Kris [Jenner] always taught her kids that they need to have very thick skin in order to handle the criticism that comes with fame,” the source told Us. “So this was nothing new and nothing Kim couldn’t take. Kim thought she handled the whole situation really well and doesn’t have any regrets about participating whatsoever. She would definitely do it all over again. Kim felt like even though some of the jokes about her were brutal, it was still all in good fun.”
