Parenthood is getting an extra injection of awesome this week as Cee-Lo stops by for a guest appearance.

In this exclusive first look at his appearance, Cee-Lo is seen touring Adam and Crosby’s (not exactly complete) studio. But despite its rough appearance, Adam wins the mega-star over by explaining the studio was once used by Janis Joplin. The only problem? Crosby seems less than thrilled with Cee-Lo’s ambitious goals.

Watch the clip below!

Parenthood airs on Tuesdays at 10 p.m. ET
