The Voice coach Christina Aguilera had a mansion in Mulholland Estates in Beverly Hills. Designed in a Mediterranean style, the home is a classic example of a “McMansion.” It has six bedrooms and eight bathrooms, with 11,107 square feet of living space in total.

The custom-designed home has features like a spa bathroom, unique fireplaces, and arched glass doorways, as well as hand-painted murals on the walls, a screening room, two bars, a large master suite, saltwater pool, and a kitchen with a huge island in it. Aguilera put the property back on the market in 2012 for $13.5 million.
