Mariah Carey christens Disney cruise ship

(CBS/AP) All aboard: Singer Mariah Carey helped christen the new Disney cruise ship Fantasy at a Hudson River pier in Manhattan on Thursday night and promised to bring her twins back to enjoy some Disney hospitality.

"I christen thee Disney Fantasy. May God bless this ship and all who sail on it," said Carey as she stood with Disney's CEO Bob Iger, and of course, Mickey Mouse.

The ceremony was held inside the ship's atrium with a fake larger-than-life bottle of champagne that sprayed the room with shiny confetti.  Carey's husband, Nick Cannon,l stood on deck with a  bottle of  real  champagne in the company of Minnie Mouse.

Earlier, Carey got a cheer from the crowd as she sang the line "I'm a native New Yorker," adding, "I'm going to love bringing my new babies here." Her twins were born less than a year ago.

At the event, Carey appeared alongside Jerry Seinfeld, New York City Mayor Michael Bloomberg, Neil Patrick Harris, Ty Pennington and Tim Gunn.

The 4,000-passenger, 14-deck ship with its distinctive mouse ears logo arrived in New York on Tuesday after traveling nearly 3,800 miles across the Atlantic Ocean from Bremerhaven, Germany. The ship, which was built in Papenburg, Germany, will sail on seven-night Caribbean cruises, starting March 31,  from Port Canaveral, Fla.
