Post her divorce with actor Tom Cruise, actress Katie Holmes is on a shopping spree. She spent a whooping $15,000 only on lingerie. “Katie treated herself to a lavish post-split pick me up shopping spree. She splurged on nearly $15,000 worth of sexy lingerie and undergarments alone,” National Enquirer magazine quoted a source as saying. “She also bought 15 pairs of pricey Christian Louboutin shoes and went on a tear at Barneys New York department store, buying a closet`s worth of clingy cocktail dresses and power suits to wear to auditions and meetings,” the source added. The 33-year-old is also trying to get back with work and doing everything it takes to revamp her career and establish her as a confident working single mother.
