Television actor and "Dancing With the Stars" competitor John O'Hurley announced Wednesday that he and his wife, Lisa, are expecting their first child.

They married in 2004.

O'Hurley, 51, is known for his role as catalog king J. Peterman on the long-running "Seinfeld" television sitcom. He also won a championship last October on "Dancing With the Stars," in which celebrities are paired with professional dancers and compete against one another in choreographed performances.

O'Hurley triumphed in a viewer-judged rematch after losing in the previous season's finale several months earlier.
