The 33-year-old, whose divorce from Cruise was finalised earlier this week, reportedly went on a lavish spending spree to cheer herself up following the breakdown of her five-year marriage, reported Femalefirst.
"Katie treated herself to a lavish post-split pick me up shopping spree. She splurged on nearly USD 15,000 worth of sexy lingerie and undergarments alone.
"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," a source said.
Holmes, who has a six-year-old daughter, Suri, with the "Mission Impossible" star, is also said to have been consulting "life coaches" to get a new direction in life.
"She wants to show the world who she really is - a beautiful, confident and talented woman balancing single motherhood and a thriving career. Now she's ready to roar, she's interviewing life coaches to help deprogram all the crap Tom filled her head with," the source added.
