Not only is "Deadpool 3" happening, but it'll also be part of the Marvel Cinematic Universe.

In an interview with Collider, Marvel Studios president Kevin Feige said the third installment would be rated R.

Feige added that actor Ryan Reynolds, who will reprise the leading role, is also working with sisters Lizzie Molyneux-Loeglin and Wendy Molyneux on the script.

Reynolds confirmed on Monday via Twitter by linking to an article with the news by quipping, "Full disclosure: I showed them Spiderman 1 & 2 and told them it was Deadpool 1 & 2. #Deadpool3."

On his other social media pages, Reynolds also confirmed the news of his character joining MCU and the movie keeping its R-rating, CNN reported.

Feige said "Deadpool 3" won't begin filming until 2022, Collider reported.
