Their Colonial-style estate is on the market.

On-again, off-again, on-again couple Michael Douglas and Catherine Zeta-Jones have just added fuel to the fire of rumors about their rocky marriage by listing their shared Bedford, NY, mansion for $8.1 million.

Most celebrity real estate watchers know that when the for-sale sign goes up in the front yard, the divorce lawyers are the next people who come knocking. With these two, who publicly split and then even more publicly reconciled, it can signal that it’s finally over for good between them, or that they’re ready for a fresh start in a brand-new home.

Whichever way they’re heading, they’re leaving behind the gorgeous mansion they purchased together in October 2010 for $5.07 million.

Located down a long gated drive, Catherine and Michael’s for-sale home is a 5.7-acre brick Colonial-style estate. Surrounded on three sides by a horse farm, the estate is quiet, private, and serene.

Generously proportioned, light-filled rooms capture the architectural details and ambiance of the 1930s. In the thick of their separation in 2013, the home was completely renovated, gaining a glorious master closet suite, gym and sauna, finely crafted moldings, hardwood floors, a state-of-the-art gourmet kitchen, and luxurious decor.

The property also now features a brand-new one-bedroom guest house with bath, kitchen, and living room.

The 5.7-acre grounds also include sprawling lawns and a sparkling swimming pool.

In addition to this property, Douglas and Zeta-Jones own homes on Central Park in New York City, in Swansea, UK, and in Bermuda, where they resided full time for many years.

Craig Siano of Siano & Co. is their real estate agent.

The Los Angeles Times first reported on the listing.
