Dream-Come-True For Mariah Carey Fan, 9

It's the stuff of a great Christmas story.

If you've ever been to New York at Christmastime, you know that Macy's "Santa Land" is a big attraction, with thousands of children lining up to meet Santa each year.

But this year, people have been visiting Macys' stores across the country for another reason: to send letters to Santa as part of the company's "Believe" campaign.

For each letter received, one dollar is donated to the Make-a-Wish Foundation, an organization that helps grant wishes to children with life-threatening illnesses.

And on Friday, Early Show viewers saw the foundation's work in action.

Nine-year-old Angelina Salaiz came all the way from Union City, Calif., and her special wish came true: she got to meet superstar Mariah Carey.

Angelina got to interview Carey, and Carey told co-anchor Julie Chen her thoughts on her own music!

Carey's latest single is "I Stay In Love," which was directed by her husband, Nick Cannon. Her latest album, "E=MC2," is over the platinum mark in the U.S.

The film "Tennessee," in limited release, features a song Carey wrote for the movie, "Right To Dream." Carey plays a waitress and budding singer in the film.
