Mariah Carey has a special keepsake from Fleetwood Mac star Stevie Nicks - a letter the rock veteran wrote her when she was struggling with her sanity.
Among the notes of support that Carey received during her 2001 breakdown was one from Nicks, and the rock star recently learned the letter has pride of place among the pop star's jewels.
She says, "I wrote her a long letter telling her how everybody else is crazy - not her.
"I saw her recently and she told me she keeps the letter with her jewellery. I love that."
