There you go. She even got the writers involved.

Erinn Hayes confirmed back in June that she was "let go" from the CBS sitcom, as Leah Remini was announced to be joining Season 2 as a series regular.

"This Is Us" Season 2 premieres September 26 on NBC. Follow #ThisIsUs for all of the Season 2 updates coming out of today's TCAs.
