She became known in 2002 for her participation to the Finnish edition of talent scouting show Popstars, where she was selected as fourth member of the girls' group Gimmel.
Jonna was successful in her solo career, but wanted to start singing in English but her record label Sony BMG did not support her proposal to now focus on English-language songs.
Jonna decided to move to Los Angeles to start working on her English-language album and find new influences for her music.
She has been making dance choreographies to her music videos such as "Tyytyväinen" ("Pleased"), "Kaikki talossa" ("All in the house"), and "Puppets".
She has worked with such song writers as Jim Holvay (The Buckinghams), Miika Colliander (Husky Rescue), Nikki Forova and Jukka Immonen.
