Jim Carrey was joking when he announced he's writing a book about depression, according to his publicist. In a recent interview, the star claimed he found prescription drugs didn't help him beat the blues and that he is currently penning a self-help guide to combat depression.

But Carrey's publicist is baffled because it's the first she has heard of a book.

She tells PageSix.com, "There is no deal with a publisher in place, and he's not actually writing a book. That is not in the plans for the immediate future."
