Singer Jill Scott , who was most recently seen in the HBO original series “The No. 1 Ladies’ Detective Agency,” has signed on to star in the Lifetime telepic “Sins of the Mother.” Production started earlier this month and the film will make it’s debut on Lifetime’s sister channel, Lifetime Movie Network, in the Spring of 2010. “Sins of the Mother” revolves around a grad student who returns home to face her abusive, alcoholic mother — played by Scott — only to discover that her mom is sober and has a 3-year-old daughter and new life. Telepic is based on the novel “Orange Mint and Honey,” written by Carleen Brice. Elizabeth Hunter adapted the novel for TV, while Paul Kaufman is directing. Damon Lee (“Obsessed”) is the exec producer for Mother Road Prods., which is behind the project. Jill will next star in Tyler Perry’s “Why Did I Get Married, Too?” — a sequel to “Why Did I Get Married.” No word yet on the fate of Jill’s HBO series. Executives at the network have still not made a decision on whether it will be picked up for another season.
