Hollywood beauty Jessica Alba has laughed off reports she is donning oversized pants and slippers to star in the film remake of I Dream Of Jeannie.

After big-budget movies THE Fantastic Four and Sin City, Alba has just signed up to appear in a low-budget film and is baffled by reports she is set to take over Barbara Eden's cult TV role.

Alba tells the New York Daily News, "I just signed on to an independent called THE WAKE for Miramax, actually, with Sigourney Weaver and Hayden Christensen.

"(So playing Barbara Eden...?) not that I know of, no."
