Glamour model Jordan is bidding to represent the UK at the Eurovision Song Contest in Kiev, Ukraine.
Jordan will be singing under her real name of Katie Price
She is one of five acts vying for the honour, alongside previous contestant Gina G and TV talent show hopefuls Javine and Andy Scott Lee.
The winning act will be chosen by the public in BBC One show Making Your Mind Up on 5 March.
Performing under real name Katie Price, she has promised to "surprise" people with the launch of her singing career.
She was first known for her topless modelling career before taking part in the t TV show I'm a Celebrity...Get Me Out of Here!, where she was seen eating grubs.
It was also during her stint on the show that she met her fiance Peter Andre.
"I'm always surprising people, so I don't think there will be any change there, and as I always say 'never underestimate the Pricey', Jordan said.
"I hope people can give me a chance to show them what I can do. It's all about representing your country which I would love to do.
"The whole country getting behind and voting for someone like me would be amazing.
"I'll do my very best. I would love to fly the flag for the UK but if I can't fly it, then I'll wear it."
Australian Gina G last represented the UK in the Eurovision song contest in 1996 with Ooh Aah... Just a Little Bit, which was voted seventh.
She said she wanted another attempt at the contest because she had been "robbed" of the winner's crown.
Operatic-style band Tricolore will complete the line-up on the BBC1 show Making Your Mind Up, hosted by Terry Wogan and Natasha Kaplinsky.
Bookmakers Ladbrokes have not ruled out a win for Jordan, but said Javine was 6/4 favourite to be chosen to represent the UK.
A BBC spokeswoman said the search for the UK entry was "stepping up a gear" after James Fox came 16th last year.
In 2003, Jemini made UK history by scoring "nul points".
Terry Wogan will again host the Eurovision Song Contest, now in its 50th year, when it takes place in Kiev, Ukraine, on 21 May.
