Britney Spear's $120,000 post-rehab surgery blitz

Pals say Britney, 25, kick-started her transformation by losing more than 10lbs during her stay at the Promises Treatment Center in Malibu last month.

Free of drugs and alcohol and exercising regularly, the pop star quickly lost her bloat and emerged slimmer and healthier, although it appears this weight loss was aided with some fat dissolving injections. But Brit still wasn't happy with the other side effects from her months of hard living.

Easter Sunday , Britney Spears celebrated her new body at a Los Angeles Lakers game at L.A.'s Staples Center.

Spears left the basketball game before halftime and headed to L.A.’s trendy Lisa Kline boutique reports US Magazine.

After Spears, 25, left the store, the salesgirls were overheard laughing about how they had asked Spears if she wanted a drink.

“I was so embarrassed after the words came out of my mouth,�? said one salesgirl.

“And then she said she just wanted orange juice so I went across the street and got her a Naked juice.�?

Across the street at Lisa Kline Women's, the pop star hit the dressing rooms and tried on various items, occasionally asking the boutique’s staff for their opinion reports US MAGAZINE

“She was proud of how she looked -- she was in great shape,�? says the source.

Spears ended up dropping $2,000 on clothes for herself.

"Britney was so happy and really friendly," store owner Lisa Kline tells Us. "She answered the shopgirls with 'yes ma'am,' and talked in a sweet southern accent and acted so polite! She looked really good, she was very put together and composed."
