Mo Collins is an American actress who plays Sister Larue in "Bad Habits".
Collins is probably best known for her work on the FOX sketch comedy MadTV where she created such characters as Doreen, the screechy-voiced mother of man-boy Stuart; the annoying and odd middle-aged woman Lorraine; and the perpetually unlucky Trina, and where she lampooned such famous faces as Alanis Morisette, Barbara Bush, Catherine Zeta-Jones, Cher, Diane Sawyer, Jennifer Love Hewitt, Jenny Jones, Madonna, Martha Stewart, Pamela Anderson, Shakira and Penny Marshall.
Collins' other credits include guest stints on According to Jim, Family Guy, and Arrested Development. Her movie credits include roles in The 40-Year-Old Virgin, Knocked Up and Jingle All the Way. More recently, she has had recurring characters on Ave 43 and Parks & Recreation.
