Paris to Makeover Britney in Her Image

Paris Hilton's tutelage of new pal Britney Spears is entering the graduate phase. Mazel tov!

While on a retail romp through her favorite Melrose Avenue boutique, trendy Sielian's Vintage Apparel, Hilton revealed that she would be bringing new BFF Britney on her next charge-a-thon. First stop: Lingerie Department, please!

Paris charged up thousands of dollars during her hour-long shopapalooza on Monday, picking up 25 "hot" dresses, 12 vintage belts, six sweaters, two purses ... and six geese a-laying.

Our source overheard Hilton graciously telling a salesperson, "Sielian's is my favorite boutique! You're the only store where I can buy this many cute dresses. I've never been able to do this at any other store" ... and that's coming from a girl with a Masters in Shopology!
