The couple, who recently celebrated their second wedding anniversary following rumours their relationship was on the rocks last year, have reportedly bought a lavish French-style property in a leafy part of Sherman Oaks.
The 7,888-square-foot family-sized mansion, situated on half an acre of land, features six bedrooms, seven and a half bathrooms, a gym, basketball court, outdoor kitchen and a gourmet eat-in kitchen with three dishwashers.
It also boasts vaulted ceilings, a number of hand-carved fireplaces, four Juliet balconies, a dramatic double stair case, an ivy-covered outdoor terrace and an over-sized swimming pool, according to Variety.com.
The couple have spent most of their time living in their native Canada since getting married in the South of France in July 2013.
