Karen Walker (née Delaney; previously St. Croix, Popeil, and Finster) is a fictional character on the American television sitcom Will & Grace, portrayed by 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 due on the popularity of the character with the audience. She was a multi-millionaire, thanks to her marriage to Stan Walker (an unseen character), until it was discovered that all of his money was loaned after their divorce in the series finale. However, at the end of the series, she regains this status. The 2017 revival of the series retconned that revelation as one of Karen's daydreams; she is still rich and still married to Stan. However, in the tenth season, Karen and Stan go through another divorce after she is caught cheating on him with his friend, a government agent by the name of Malcolm Widmark (Alec Baldwin), she struggles with her loneliness and erratic emotions. Karen has been described by Grace Adler (Debra Messing) as "a spoiled, shrill, gold-digging socialite who would sooner chew off her own foot than do an honest day's work." She is also a promiscuous alcoholic/drug addict with an often tenuous grip on reality and very few morals. She’s best friends with Will Truman’s (Eric McCormack) equally narcissistic friend Jack McFarland (Sean Hayes). After Mullally spoke her lines in her normal speaking voice in the pilot, she increased her delivery in pitch in subsequent episodes until her distinct nasal voice, became one of the character's trademarks. In 2010, Karen Walker was ranked No. 23 on the TV Guide Network special 25 Greatest TV Characters of All Time. Fictional character history Early years Karen Delaney was born on January 12, 1959 (which is revealed in the show's season 8). Karen had a difficult childhood, thanks in part to her unstable relationship with her mother, Lois Whitley (Suzanne Pleshette), a con artist who incorporated her young daughter into her schemes. Karen has made many references in the show to her education and her maiden name, Delaney, which suggest she is of Irish-American background. Although she tries to keep her age a secret, Jack 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 husband was named
