Karen Delaney St. Croix Popeil Walker Finster-Walker was a fictional character on the American television sitcom Will & Grace (1998-2006). She was portrayed by actress and singer Megan Mullally.
Although Karen was originally conceived as a supporting character role for Will & Grace, her escapades became a more prominent part of the show based on positive viewer reaction. She was a multi-millionairess thanks to her marriage to Stan Walker (an unseen character) until discovering he was broke.
Karen was born on January 12, 1959 (which is revealed in the show's season 8). Karen's childhood was a rocky road, thanks in part to her unstable relationship with her mother, Lois Whitley (played by Suzanne Pleshette), a con artist who incorporated her young daughter into her schemes. Although she tries to keep her age secret, her good friend Jack McFarland revealed that she was 42 in 2001, meaning she was born in January 1959. She has been married four times — her first husband's surname was St. Croix, her second was named Popeil (a reference to the American culinary businessman/entrepreneur Ron Popeil), her third was Stan Walker (married since 1995), and she was married for 20 minutes to Lyle
