From lunches at the Plaza to $850 Ferragamo purses, Suri Cruise knows how to live life to the fullest.

So, in honor of her sixth birthday, the mini A-lister headed to a Broadway show with mom Katie Holmes, where the mommy-daughter duo caught a Newsies matinee.

"Katie seemed happy that Suri was having a great time," an eyewitness tells Us Weekly of the pair. "Suri loved the dance numbers...she was one of the first in the audience to start clapping along!"

Last year, Holmes and husband Tom Cruise feted their only child's fifth birthday with a posh, tea party-themed bash in Beverly Hills.

The Kennedys star, 33, explained she settled on the theme because she "kind of likes to girl it up."

Admitted Holmes, "[Suri's birthday] is my favorite day of the year!"
