Sheryl Lee Ralph, who originated the role of Deena Jones "Dreamgirls" and is married to Philly/Montco State Senator Vincent Hughes, has booked a new sitcom. Ralph will play the mother of Tia Mowry in Nick at Nite's "Instant Mom," about a 25-year-old party girl who gains an immediate family after she marries a man with kids. Duane Martin will play Mowry's new hubs.

Mowry, who announced that she would not be returning to BET's "The Game," is no instant momma: She has a son, Cree Hardrict, who is one. Her pregnancy was the subject of the first season of the utterly watchable reality show, "Tia and Tamera," which she appeared in with her twin and "Sister, Sister" co-star.

This isn't the first time Ralph has played mom to a '90s icon: She was also Brandy's mom on UPN sitcom "Moesha."
