She beat glamour model Jordan, who was favourite to win, into second place with her song Touch My Fire.
Javine, who was "gobsmacked" at her victory in the televised contest, will compete at the finals in Kiev, Ukraine.
Meanwhile Casualty actor Christopher Colquhoun became the fifth student to be kicked out of Celebrity Fame Academy, being held for Comic Relief.
The 34-year-old, who plays Dr Simon Kaminski, was favourite to be voted out and follows in the footsteps of Jon Culshaw, who departed the BBC One show on Friday.
If Jordan, who entered the Eurovision contest under her real name Katie Price, had won, she would have been eight months pregnant by the time the contest came around.

Javine first found fame on the Pop Stars: The Rivals show when she lost out on a place in the line-up of Girls Aloud.
She has since had four top 20 singles as a solo artist.
Also performing for a Eurovision entry on Saturday night was former Pop Idol contestant Andy Scott Lee, who sang Guardian Angel.
Gina G, who represented the UK in the 1996 Eurovision Song Contest, was the voters' least favourite act on the night.
Radio One DJ Edith Bowman is favourite to win Celebrity Fame Academy on Comic Relief Night this Friday.
Eight celebrities remain on the show and will battle it out every night until the finale on 11 March.

After being eliminated, Colquhoun, 34, said he was disappointed to be going but said taking part had been the "most fantastic experience".
Of the other contestants, he backed comedian Gina Yashere - who the contestants had voted to save after a public vote - to win.
He added: "I think they are all superb. They were all fantastic on the night and deserved to go through."
