A new marriage has apparently not done much for Justin Bieber’s fear of commitment. The Canadian pop singer is dropping nearly $100,000 a month to rent a 7,000-square-foot home in the San Fernando Valley enclave of Toluca Lake. Bieber agreed to rent the home, which is listed off-market for $8.5 million, in a short-term arrangement that pushed up the monthly fee. The home’s owners, Howard Atkins and Kathleen McIntyre of San Francisco, bought it for $4.9 million in 2009, according to property records. Atkins is a former CFO of Wells Fargo & Co. The Spanish contemporary home was overhauled two years ago, which boosted the square footage. It now has five bedrooms and seven baths, and a 1,200-square-foot garage. More importantly for the singer, it has a professional recording studio, along with a pool, spa and private dock with two paddle boats. Bieber’s master suite features a massive walk-in closet and a luxurious spa-like bathroom and windows that showcase the home’s lake views.
