Cheer's Monica Aldama isn't just an executive producer on NBC's mockumentary Stumble - she also has a surprise cameo. In Us Weekly's exclusive clip from the Friday, November 7, premiere, Aldama, 55, is seen in the background as Courtney (Jenn Lyon) announces her departure as head coach of the college cheerleading team. "I have been asked to be fired," she says as assistant coach Tammy (Kristin Chenoweth) breaks out in sobs. "Come on, there is no crying in cheer. I need you to be strong." While one of the students threatens to leave along with Courtney, the head coach isn't as supportive.
