Suri Cruise has learned quickly how to fend off the paparazzi. And one "professional" autograph-seeker has learned he will curry no favors for calling an adorable 7-year-old celebrity "a little brat."

The daughter of Tom Cruise and Katie Holmes was swarmed by a crowd while stepping out with a friend and her mom Thursday. The trio were waylaid by the photographers and autography-seeking fans.

Fishwrapper released video showing Suri yelling to the crowd "We're trying to get in the car. Stop it" and "Get out of the way."

On video taken by photographer Cesar Pena of 247paps.tv, a male voice is heard saying, "Bye, Suri, you little brat," as the child climbed into a waiting SUV.

Pena is heard saying "Whoa, whoa, whoa" repeatedly to the man -- whom he described to Us Weekly as a guy who sells celebrity autographs on eBay.

"When you're a father, bro, it's a whole different thing," Pena told the man. "It's a whole different thing."

The man replied, "I don't care... She's a (expletive)... a little brat kid. A little brat."

Pena later explained to Us Weekly that the autograph-seeker was too "in Suri's face" and that he and some of his paparazzi colleagues are protective of the young celebrities they photograph.

"I have a little girl, so it triggered quick for me," he added. "I saw her as my own. She's only 7 years old... I went into Daddy mode quick."
