Mary Elizabeth Ellis

Mary Elizabeth Ellis was best known for playing The Waitress on "It's Always Sunny In Philadelphia" (FX 2005), but as her Twitter bio said, the funny actress was so much more than that. Ellis was born in Laurel, Mississippi. She began acting as an elementary school student, where she starred in local theater, continuing to pursue her love of drama into college at the Meadows School of the Arts at Southern Methodist University. After graduating in 2001, she moved to Los Angeles, where she studied and performed at the famous Upright Citizen's Brigade and took on a few minor TV roles. In 2005, she landed a recurring role as The Waitress in the offbeat "It's Always Sunny in Philadelphia." The character Charlie Kelly, played by series co-creator Charlie Day, was obsessed with The Waitress, despite the fact that she can't stand him. Humorously, Day and Ellis married in 2006. Ellis later co-wrote and starred in the independent romance "A Quiet Little Marriage" (2008) and landed a starring role in the short lived sitcom "Perfect Couples" (NBC 2011), playing Amy, one half of a passionate and dysfunctional couple. In 2011, Ellis gave birth to her and Day's first child, a boy named Russell Wallace Day. She made guest appearances on a variety of comedy shows, playing a sexy medical examiner on "Brooklyn Nine-Nine" (Fox 2013-) and a sad sack ex-girlfriend on "New Girl" (Fox 2011-).
