R+B singer TAMIA and her basketball star husband Grant Hill have confirmed they're expecting a second child. The Canadian Grammy winner, real name TAMIA WASHINGTON-HILL, is four months pregnant and decided to reveal the happy news on her MySpace.com page because she feared she couldn't hide her swelling belly any longer. She writes, "I'm happy that the secret is out because it was getting very difficult to hide it. "I performed yesterday (15MAR07) and I caught a glimpse of myself in a reflection and I thought, `Oh no, I'm going to have to talk about this.'" The happy couple wed in 1999 after they were introduced by soul star Anita Baker. They already have a five-year-old daughter, MYLA.
