Katie's shopping away the breakup blues

If she’s down about her topsyturvy love life, a radiant Katie Holmes isn’t pouting — instead she’s saying “buy buy” with a shopping spree this week in Soho. As Page Six reported on Monday, Holmes, 37, and secret squeeze Jamie Foxx, 48, split up because he couldn’t commit. “Jamie wants to continue to act like the carefree guy he is in public,” a source said.
