Fans who have been looking forward to seeing Mariah Carey and Janet Jackson hit the big screen together for Tyler Perry's film adaptation of Ntozake Shange's 1975 play "For Colored Girls Who Have Considered Suicide When the Rainbow Is Enuf" will be disappointed to learn that the flick is officially one diva short.

A rep for Carey confirmed to People.com that the singer decided not to appear in the flick this week, following Perry's confirmation of the cast to MTV News in April. Her rep, Cindi Berger, gave no concrete reason her departure but said, "I'm not at liberty to discuss her personal life at this time."

Her dropping out of the film has many wondering if Carey is pregnant, a rumor that has been following her around since she married Nick Cannon two years ago. That rumor has to date not been confirmed.

Shooting for the film is expected to take place in New York City this summer, and the film will hit theaters in late 2010 or early 2011. Earlier this year, Perry (and Janet Jackson) listed the names of the women attached to the movie, which at the time included Carey. "It's Janet, Mariah, Whoopi Goldberg, Phylicia Rashad, Jurnee Smollett, Kimberly Elise, Kerry Washington, Loretta Devine, Anika Noni Rose ... I don't want to forget anybody," Perry said. "It's pretty incredible."

The play "For Colored Girls ..." is a series of 20 poems telling the stories of seven different women, each of whom is identified with a color of the rainbow. The stories deal with a wide spectrum of topics including love, abandonment, rape and abortion.
