Jill Scott, 36, is pregnant with her first child, the R&B singer and actress revealed to reporters at the Television Critics Association conference in Los Angeles on Friday. Promoting her new HBO series The No. 1 Ladies' Detective Agency Scott said she discovered that she was pregnant just before leaving for Botswana where she filmed the show. "The first trimester I spent in Botswana," said the star, who is due April 25. "That was one of the biggest challenges of my life. First trimester! You're sick every morning. It was seven hours time difference, the heat, the bugs, the 14 hour days." Still, the actress, who is engaged to drummer Lil' John Roberts, says she's glad she went through with the plans to film. "My doctors gave me a clean bill of health and said you can do this, so I did it."
