*Word has it that newlyweds Mariah Carey and Nick Cannon are planning a $4 million wedding ceremony for the benefit of family and friends who weren't invited to the secret nuptials last month at her Bahamas retreat.

      MSNBC.com is quoting "a source" who claims that Mariah "wants over 2,000 guests and the budget will be well over $4 million and she'll have at least 14 bridesmaids. 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 right on track."

       Meanwhile, the New York Post's Page Six reported yesterday that Nick "was trying to have a boys' weekend at Saturday's opening of the MGM Grand at Foxwoods with pals Sean Combs and Quincy Jones when he got a call from Carey."      

       The column quotes "a source" who said: "[Nick] was summoned home by her at 1 in the morning. He didn't look happy about it."
