'Laguna Beach's' Kristin Cavallari lists in, well, Laguna Beach

In the real Orange County, not everyone ends up living in their custom-built home.

The intended family residence of actress Kristin Cavallari has come on the market at $13.95 million in Three Arch Bay, a gated Laguna Beach community.

Cavallari was playing herself in 28 episodes of "Laguna Beach: The Real Orange County" (2004-05) during part of the eight-year construction period but never occupied the feng shui-savvy residence. And in what may seem to blur the lines between reality and reality TV, the home was designed by architect Jim Conrad, father of fellow cast member Lauren Conrad, who went on to star in "The Hills" (2006-09).

The newly built contemporary has four bedrooms and six bathrooms in 7,100 square feet and sits on 3.25 acres with views of Catalina and the coastline. Natural stone -- more than $2 million was spent on masonry -- and hardwoods were used extensively in the construction. There is an infinity pool, nearly an acre of landscaped grounds and gardens, and parking for 25 cars.

Cavallari, 22, became a spokeswoman for the clothing company Bongo and continues to act in film and TV, as well as host and take part in reality shows.

Now "The Hills" universe is buzzing with speculation that she may be appearing in the show next season just as Conrad, 23, is wrapping up her role in the May 31 episode. MTV isn't saying.

Chris Guziak of Coast Sotheby's International Realty, Laguna Beach, has the listing.

Dinah Shore's onetime digs

The Palm Springs house of sitcom writer-director-producer David Lee has come on the market at $5,995,000 in the Old Las Palmas neighborhood.

The renovated 1963 estate, designed by architect Donald Wexler for big band-era singer and television show host Dinah Shore, sits on 1.3 acres. The 7,000-square-foot Modernist showplace has six bedrooms and 7 1/2 bathrooms. There are floor-to-ceiling glass walls, wooden ceilings, a massive stone fireplace and a sunken bar in the living room.

Although there's a tennis court and a pristine swimming pool, the sport that the Emmy-winning Shore is most often associated with is golf. A player herself, she helped found one of the major tournaments on the LPGA tour.

Lee partnered with Peter Casey in writing and producing "The Jeffersons" for six years and "Cheers" (1984-93). Along with David Angell, they created the Emmy-winning series "Frasier" (1993-2004). More recently he has turned to the theater, directing revivals including "South Pacific" at the Hollywood Bowl.
