PIC: Tom Cruise and Suri Go for Teacup Ride at Disneyland!

Mission: Adorable!

Tom Cruise treated daughter Suri, 5, to a rollicking day at Disneyland in Anaheim, Calif. on Wednesday.

Sans wife Katie Holmes, the Mission: Impossible - Ghost Protocol star, 49, and his little girl "were having the cutest dad and daughter outing together," an onlooker tells Us Weekly. In one super-cute pic, the proud papa and his little girl (with her face painted) took a spin on the Mad Tea Party ride -- aboard a girly-girly pink teacup, of course.

"They were just having the cutest dad and daughter outing together," the witness says. "Tom was spoiling her rotten! He let her get her face painted and bought her a bunch of souvenirs."

The mini-fashionista's favorite part of the park? "Fantasyland," the witness says. "Because it was where all the princesses lived!"

Suri "loved all the Fantasyland rides," the observer adds. The twosome went on the Storybook Land Canal Boats, It's a Small World, and King Arthur’s Carousel.

"Tom had a huge smile on his face the entire time and doted on Suri," the observer notes. "He was pointing favorite things out to her, holding her hand, and picking her up so she could see over the crowd."

And despite their A-list status, the superstar "wasn't demanding at all…He couldn't have been more appreciate and nice to everyone there."
