Nick Cannon sends Mariah Carey love letters every day.

The presenter-and-rapper - who married the singer in April 2008 - revealed he collected all of their notes and had them printed in a special book to mark their first wedding anniversary last year.

He said: "She likes to be inspired. She is an emotional, sensitive woman. You need some daily inspiration.

"On our first date, I promised her that every single day, I would write her an email, call her, send her a text with an inspirational message and from that day forward I did it every single day.

"On our first anniversary of our wedding, I took all those messages and bound them in a book. Romantic!"

As well as being inspired by Nick's messages, Mariah recently revealed she had grown more confident after wearing no make-up for her role in 'Precious: Based on the Novel Push by Sapphire'.

She explained: "I think it was crucial to dress down. It was tough because making music videos is so different with the costumes, the angles, the lighting, stuff like that.

"In 'Precious', we sat in a fluorescent dentist's office and it was the worst-lit scene of the movie. The over-lighting emphasizes the dark stuff under your eyes.

"I guess now I'll feel better about myself when I'm dressed normally at my house and walk past a mirror and see myself. I'll be like, well I've looked worse."
