Suri Cruise in Wonderland!

The stylish tot celebrated her 5th birthday with a lavish tea party at her parents' Beverly Hills Mansion on Sunday.

Wearing a frilly pink dress and turquoise sunglasses, Suri -- famous for her high-priced couture ($850 Ferragamo bags, $635 dresses) -- sat at the head of the table, surrounded siblings Connor, 18, and Isabella, 16 (among other guests). See more photos from Suri's party.

Why the tea party theme? "I kind of like to girl it up!" mom Katie Holmes, 32, explained two weeks ago. "This is my favorite day of the year."

The birthday girl made a few requests of her own, too.

"She wants a pinata and her girlfriends to come over [to go] swimming," The Kennedys star said. "We're gonna make a cake together!"
