The Happiest Place on Earth just made one little girl very happy indeed.
The 6-year-old was clearly in her element while making her way around the park with her dad and Tom's sister, Cass Mapother, as excited tweeters were quick to snap photos of the darling girl in all her costumed glory.
We knew she was treated like a princess; it was only a matter of time before she started dressing the part. Katie Holmes' Mini-Me did just that, strolling the grounds while all dolled up as Ariel from The Little Mermaid.
Well, she is Hollywood royalty, after all.
