Catherine Zeta-Jones and Michael Douglas are in talks to sell their Westchester estate to Aussie cardboard billionaire Anthony Pratt, of Pratt Industries.

The power couple bought it for around $11.25 million in 2014 and are in contract to sell it for around $15 million in an off-market deal, Gimme Shelter has learned.

The palatial 15,458-square-foot residence at 44 W. Patent Road in Bedford Corners was built in 1895.

It features eight bedrooms and an incredible 18 bathrooms, all on 13.28 acres.

It includes a handsome chef’s kitchen, plus a spa with two indoor pools, a gym, a sauna and a steam room. Zeta-Jones renovated it room by room, sharing photos on social media throughout the process with the hashtag #StyleByZeta. Per Instagram, Zeta-Jones converted a barn on the property into a “girl cave” with a ballet barre and mirrors, a sewing machine and a large sofa.

Outside, there’s another pool, a tennis court, a guest cottage with two apartments and a greenhouse. We hope Pratt is a horse lover; the estate additionally delivers a four-stall barn, an outdoor ring, four paddocks and direct access to the Bedford Riding Lanes trails.
