Britney Spears splashed out over $3,000 on clothes for her and her kids Sunday (left) after staff at trendy Los Angeles store Lisa Kline agreed to ask customers to leave so she could shop in peace. The pop superstar arrived unannounced at the boutique after attending an Easter Sunday afternoon basketball game between the Los Angeles Lakers and Phoenix Suns. Spears bought a camouflage pants-and-top set and swimming trunks for her baby son Jayden James, and Wes and Willy shorts and Converse sneakers for her older son, Sean Preston. She even treated her Chihuahua Bit Bit to a green Moses Basket, according to People magazine's Web site. Employee Kate Levington tells the publication, "She was lots of fun to shop with. We had music on in the stores and she danced to the music. ... You could tell she enjoyed herself."
