So Britney Spears has a new addition to her family. It was reported that Britney Spears picked up a Yorkie at a pet store in Bel Air and named it London.

A patron of Pets Of Bel Air, who was in the store at the time said, She [Britney] picked up the dog and loved it right away, she was incredibly nice and very pleasant.

Britney Spears did the same thing last December when she first saw a six-bedroom, six and a half-bath house in Beverly Hills. According to sources, Britney reportedly shelled out $7.2 million for the house and all of its furnishing right on the spot. Impulsive? No way! After one month she raised the asking price and put it on the market. Britney lowered the price because of lack of interest. Britney then took the estate off the market, while at Promises. Then she changed her mind once again and decided she doesn’t want it anymore. She put the house and all its furnishings on the market for $7.495 million. This property is not her only one in need of a buyer; the Malibu house she lived in with Kevin Federline is up for $11.9 million. So where is Britney living with her new puppy? It’s been rumored that she’s renting a new house in Bel Air.
