Congrats to Mariah Carey and Nick Cannon. Not only did they have their twins today at 9:07am pacific, they also got lost inside the hospital after arriving in their Rolls Royce Phantom. And it’s their wedding anniversary. As their rep Cindi Berger told me: “It was like something out of I Love Lucy.” No names yet, but they’re bound to be interesting. This has been a long haul for Mariah, who’s 41, and has been married to Nick for two years. You’ll recall her great career launch in 1989, followed by an unhappy marriage to her mentor, Tommy Mottola. When she tried to break free of Mottola and get into hip hop, critics and fans went crazy. Then she got in acting, and made “Glitter,” unintentionally hilarious. It looked like curtains for Mariah, but she came back strong first with the album “Charmbracelet” and then “The Emancipation of Mimi.” The latter was such an outsize enormous hit that it brought her back twice has big as before. And now the happy ending: twins. Plus she’ll have a new album before the end of year. After that. Carey will likely join L.A. Reid and return to Sony Music. Whew!
