What to get a famous five-year-old who already has everything, including a $150,000 shoe collection? Tom Cruise and Katie Holmes have purchased a $100,000 tree house for their daughter, Suri Cruise. How can a tree house be so expensive? Well, this one has running water, electricity, security cameras, shag carpeting and a team of nannies. Suri was even allowed to decorate and design it. “It may sound funny, but Suri now has her dream home,” a source told In Touch magazine. “She hosts tea parties there on fine china and watches TV with friends.” At left, Suri and Katie enjoy a play date at a Malibu beach.
