Phil 'CM Punk' Brooks was alledgedly backstage during the press conference for All In, according to host Jenn Sterger.
Sterger said how Punk was backstage to pick up merchandise from Pro Wrestling Tees, but said fans would lose their minds if they knew.
She said: "I just kept thinking ‘if they knew you were back here, they would literally tear down the front of the store.'"
Punk left WWE in January 2014, and has stayed away from all pro-wrestling events since.
The former WWE Champion is scheduled for a fan meet-and-greet in Chicago, IL, one day before All In.
Speaking on All In, Sterger said how the independent super-show is arguably the best thing in the world.
"If you got your tickets at face value for this event, I’m just saying it literally might be the best in the world,” she said.
All In will take place on September 1 in Chicago IL, and will feature stars like the Bullet Club, Kazuchika Okada, Jay Lethal, actor Stephen Amell and more.
