Leave it to Mariah Carey to take things to the next level. The singer is getting ready for a lavish, over-the-top second wedding to her husband, Nick Cannon. "It's going to be held in New York City in the next six weeks. Picture a wedding on the scale of Liza Minnelli's [to David Gest] and you'll be on the right track," an insider tells msnbc.com's The Scoop column. Her April 30 wedding to Nick in the Bahamas was small and intimate with guests who were "mainly people there to do my hair and help me with the dress," she told Ellen DeGeneres. This wedding should satisfy all of Mariah's fairy-tale fantasies. "She wants more than 2,000 guests and the budget will be well over $4 million, and she'll have at least 14 bridesmaids," says the insider.
