British director Jeff T. Thomas is set to be a father - his designer wife Kahi Lee is pregnant.

Lee, who is featured on U.S. reality show Design on a Dime, is due to give birth to the couple's first child, a baby girl, in March (13).

The expectant couple tells, "We are beyond thrilled and feel incredibly blessed as we eagerly await the arrival of our little lady."

Thomas, who has taken charge of episodes of crime dramas Csi: Ny and Without a Trace, has been with Lee since 2010.
