After appearing on The WB's supernatural drama "Charmed", where he played the recurring role of Dex Lawson, a love interest (and brief husband) of Phoebe Halliwell (Alyssa Milano), it was announced on December 5, 2006, that he would guest-star on episodes of "Brothers & Sisters" as a possible love interest to Matthew Rhys' character Kevin Walker. He signed on to do seven episodes to play Chad Barry, a closeted gay soap opera actor who finds it difficult trying to develop a relationship with Kevin while keeping his sexuality secret from the Hollywood press. He reprised the role in an episode in April 2009. He also played a soap opera actor on two episodes of "House". Lewis appears and is highlighted on the cover in the limited-edition coffee table book "About Face", shot by celebrity photographer John Russo and published by Pixie Press Worldwide.
