Long before she became famous thanks to the success of 'American Idol' and the movie 'Dreamgirls' Jennifer Hudson sang on cruise ships for a living, and now that she's a star has decided to perform a series of concerts for the Carnival Cruise Lines. The tour 'Carnival Live' will start, said the singer at a press conference in Manhattan, on June 18 and June 19 Carnival Ecstasy and will continue on the Carnival Breeze, both in Cozumel, an island of the Caribbean Sea, just off the Peninsula Yucatan. The performances of Hudson are part of a program of Carnival to regain customer confidence after a series of incidents that have greatly undermined the image of the company. Jennifer has performed in Manhattan during the conference in a number of successes including the song 'One night only'.
