One Last Time Ariana Grande
Cheryl Cole will be teaming up with Prince Charles today.
It's to celebrate young people who've overcome difficulties to turn their lives around. Their achievements in battling things like homelessness and drug addiction will be recognised at a ceremony this afternoon.
They've been helped by Charles' charity the Prince's Trust.
As well as Cheryl, other ambassadors including Dermot O'Leary and Christine Bleakley will be there.
In February Cheryl met Prince Charles to discuss a project to help disadvantaged young people start up their own businesses in Newcastle and surrounding areas.
Cheryl told the Press Association, "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."
