Ke$ha

Kesha Rose Sebert (born March 1, 1987), known as Ke$ha, (pronounced /ˈkɛʃə/) is an American singer, rapper, and songwriter.

Alla is a big fan of Ke$ha. In Gohar's Gohar, after Alla threatens to blow the "Ke$ha Big Sister Whistle," Ke$ha protests that her voice isn't that high. Then, Alla pops up in front of the frame and says "Who cares?".

Ke$ha is mentioned in Daydream With Me, when Meri asks Erna about the meaning of Ke$ha.
