CM Punk arrived to the FOX lot in secret this week for a surprise appearance on WWE Backstage ... and the whole thing was documented in a cool behind the scenes video.

WWE on FOX's Twitter account shared the video which begins with Punk talking about meeting with FOX executives about his role on the show. The former WWE champion says he was told they want him on the show as an analyst, similar to A-Rod with MLB coverage and Troy Aikman with NFL coverage. 

Punk is shown arriving to the lot shortly before Backstage was set to begin and hiding his face with a scarf to make sure the secret wasn't spoiled beforehand.

Prior to making his first appearance on the show, Punk is shown in the elevator saying "this is kind of a big deal." When someone in production reaffirms that he IS kind of a big deal, the former wrestler replies saying, "For the first time, I will say yes. I will admit that. This is kind of a big thing."

Watch the full video below to see CM Punk watching the show before his intro and more.

WWE Backstage airs Tuesday nights on FS1 at 11pm ET/ 8pm PT.
