The 27-year-old X Factor judge recently met with Prince Charles at Clarence House in London to discuss plans for the new foundation, which she is set to start work on in April.
The new foundation will help young people to get the most out of their lives and it will help fund the Trust's work in her hometown of Newcastle.
Speaking about the new project, she said: 'Too many young people grow up thinking no one cares and don't believe they can make anything of themselves.
'They have so much potential - but can go off the rails without the right care and support. I want my Foundation to help them realise their potential and get their lives on track.
'I have always been a great admirer of the work of The Prince's Trust with disadvantaged young people across the UK. It's the perfect charity for my Foundation to support.'
