Gaga’s 6,143 square- foot Mansion If you had to guess where Lady Gaga lives when she’s in Hollywood, the answer is very simple - she rents a house in Bel Air. A 6,143 square-foot mansion with a huge pool and jacuzzi tub costs her $25,000 a month, and it features marble and expensive wood. The double height entrance has marble flooring and a curving staircase. The two-story living room has French doors. Carved stone mantelpieces decorate both the living and family room. A room that can be used both as office and library has built-in shelves and French windows that lead to the pool terrace. The kitchen consists of two separate areas one of which is for cooking and the other for dining. Its glass doors lead to an outdoor area with tables and chairs. All in all there are six bedrooms and eight bathrooms besides the pool, office, and closet. The interior design is simple and modern, with traditional style accents in furniture and interior accessories. The color scheme for all rooms is white and cream white.
