Since the Carter twins are most likely needing a bigger house, the couple reportedly had a secret viewing of the 57,000-square-foot, French chateau-style home.

According to W Magazine, the house belongs to British Formula 1 heiress Petra Ecclestone and her husband, billionaire businessman James Stunt.
They purchased it for $85 million in the summer of 2011.
However, the estate is most famously associated with the late producer Aaron Spelling and his wife Candy, who built 'The Manor' property in 1991.

After Aaron's death in 2006, Candy listed the home for $150 million in March 2009.
According to the listing, this home is "amongst the most exceptional properties in the United States."
