Just when you didn’t think the cast of Showtime’s series “Shameless” could get anymore badass, actor Ethan Cutkosky made a surprise appearance last weekend at the Reaction NYE festival and Umphrey’s McGee in the Chicagoland area.

Cutkosky plays “Carl,” a snot-nosed, mischievous teen with a heart of gold. The U.K.-turned-U.S. dramedy “Shameless” is about an unconventional family’s hardship and hustle residing in Chicago’s South Side. Ironically, Cutkosky is the only star of “Shameless” that is a true Chicagoan, more specifically a native of St. Charles, Ill.

“Carl” took pictures with fans sporting a disheveled hairdo, Bassnectar emblem, goofy smile and a confession for his love of GRiZ concerts. Aficionado, Jake Kantor said “Let’s get this dude to Scamp!”
