Actress/comedian/singer played by Jane Krakowski in the TV sitcom 30 Rock. In the first-season episode "Jack-Tor" (first aired 30 Nov. 2006), she reveals that her "My Humps"-esque pop song "Muffin Top" was number 1 in Israel and number 4 in Belgium.
In the sixth-season episode "Kidnapped by Danger" (first aired 22 March 2012), she is infuriated by Weird Al Yankovic's parody of her song "Kidnapped" (as "Knapsack"). She records a song so ridiculous it can't be parodied ("Fart So Loud"), but Weird Al manages to "Normal Al" it into a serious song.
She plays Janet Jopler in a network bio-pic.
