Column Idol 2012 offers six writers aged 18-25 the opportunity to be mentored by journalists at The Sun, with one lucky winner earning the chance to have their writing published in the newspaper.
Price, who has been writing her column in The Sun for nearly three months, said: "Column Idol offers an amazing chance for young people to stand up for what they believe in and to put their opinions across. My advice to entrants is don't let anything hold you back."
The scheme - jointly run by the Media Trust and The Sun - offers candidates the chance to be mentored by professionals who will give them advice on their ideas and help them with their column writing.
The six shortlisted writers will present their work to a panel of judges including The Sun's editor Dominic Mohan and Lorraine Kelly. The winner of the final stage will get their column published in the newspaper in September 2012.
Mohan said: "The Sun is committed to finding and investing in new talent so I am extremely proud that we are giving new voices a platform through Column Idol 2012.
"Each year we have attracted incredible talent from all walks of life and I'm sure this year will be no different."
Katie Lloyd, Deputy Chief Executive at Media Trust, said: "We're pleased to partner with The Sun to find raw undiscovered talent and give young people the chance to get their voices heard."
The competition, which is now in its third year, has previously been supported by Dizzee Rascal and Jessie J.
