The Geordie X Factor star worked a chic monochrome coat, which she wore over a black shift dress, teamed with Louboutin peep-toes.
She finished her right royal look with an outsized updo, and dangly earrings.
Cheryl met Prince Charles for afternoon tea at Clarence House to discuss her plans to help needy teenagers in her hometown of Newcastle through the Prince's Trust.
Cheryl said: "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.
"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."
Charles' flagship charity has been helping disadvantaged young people start up their own businesses, return to education or gain life skills since being founded by the royal in 1976.
Now, he will act as Cheryl's mentor as she fulfils a 'long-held ambition' to help disadvantaged young people from the North East through the Cheryl Cole Foundation.
In return, she is expected to give the Prince's Trust a million-dollar boost with her huge star status .
