We've got music superstar Mariah Carey backstage after her big appearance on Thursday's "Rachael Ray."  The singing powerhouse is dishing to ET about everything from her marriage to actor Nick Cannon, to how to maintain a good relationship, to her favorite dish to make for him -- linguini with white clam sauce!

"Married life is great. [Nick] is a great person. He's very smart, he's very loving. He's [a] caring, incredible person. We have fun, that's the thing. We just have a great time together."

She also talks about her new fragrance Luscious Pink, and about her exciting new contest for fans: "I love to get my fans involved in what I do whenever I possibly can. So this time around with Luscious Pink coming out ... they can design a dress for me," she says. 

Mariah will wear the winning dress at an event and will then auction it off, with proceeds going to breast cancer awareness. To submit your design idea and to learn more Luscious Pink go to www.mariahcareybeauty.com. And catch Mariah Thursday on "Rachael Ray."
