Britney Spears went on a shopping spree last week to celebrate losing over half the weight she gained while pregnant with her second child. The 24-year-old was browsing in Malibu, California, boutique Planet Blue on October 9 and snapped up 45 pieces for her new svelte frame.

Five weeks after giving birth to son Sutton Pierce, Spears has reportedly dropped 26 pounds - without a trainer, diet pills or a nutritionist. A family friend of Spears says, "She is not treating herself with food and desserts anymore."

According to an employee at the store, the star gushed that she was "a whole new size - an eight," and needed "all new clothes." Spears weight reportedly jumped from 120 to 160 during her pregnancy, but has slimmed down with diet and exercise.

Another store employee, Jenny Rossi, tells publication Us Weekly, "She requested T-shirts, jeans, sweaters, dresses and coats."

Spears, who is working out six days a week, hits the treadmill each morning, followed by weight lifting and then does sit-ups in the evening. She is also taking off the excess weight with a diet of six small meals a day, ditching her love of fast food for healthy snacks like fruit, nuts and low-fat yogurt.

Spears hard work has apparently paid off, according to husband Kevin Federline's representative Mike Esterman: "Kevin loves the way Britney looks."
