Lennon co-created and starred in her own ½ hour USA series, Playing House, which just concluded after 3 critically acclaimed seasons. She also recurred as Julia Louis-Dreyfus' hilarious Senior Advisor, "Karen Collins," whose specialized field was "common sense" on HBO's VEEP. Additionally, Lennon has made a number of memorable appearances on television including Fox's Ghosted, Netflix's Lady Dynamite, AMC's Mad Men and NBC's Parks and Recreation. On the feature side, she also had flashy supporting roles in Horrible Bosses 2, Confessions of a Shopaholic and Other People.
