McHale has signed a new multimillion-dollar contract that will see him stay on the show for "at least two more years" as well as develop non-scripted projects for E! through his new company Free Period Productions, according to The Hollywood Reporter.
The Soup is currently airing its ninth season, and will premiere its tenth season in January.
McHale, who stars in NBC's Community, previously signed up for the biker drama Sons of Anarchy. He plays a conman who double-crosses the wrong person.
He joked that his addition to the drama will "bring this whole thing to a screeching halt".
Sons of Anarchy is currently on its fifth season, which airs on Tuesdays at 10pm ET on FX.
