Paris Hilton, the blond, doe-eyed celebrity thrust into the presidential campaign in an ad by Republican candidate John McCain, issued a tart rebuttal Tuesday, albeit in a scantily clad, tongue-in-cheek kind of way.

Last week, McCain launched an ad comparing Democratic rival Barack Obama to Hilton and Britney Spears, suggesting Obama was no more than a celebrity candidate unready to lead the nation.

Hilton initially shied away from the debate over the ad and its effectiveness. But she agreed to shoot the video after being approached by the Web site Funny or Die, its content director Amy Rhodes told The Associated Press.

Rhodes said Hilton was not compensated for appearing in the video because she decided she just wanted to do it for fun.

Before Hilton appears, an announcer calls McCain "the oldest celebrity in the world, like super-old, old enough to remember when dancing was a sin and beer was served in a bucket," and asks, "but is he ready to lead?" Hilton's spoof also intersperses images of McCain and Yoda from "Star Wars" and the cast of television's "The Golden Girls."

Then Hilton herself appears reclined in a pool chair in a revealing bathing suit and a pair of pumps, saying, "Hey America, I'm Paris Hilton and I'm a celebrity, too. Only I'm not from the olden days and I'm not promising change like that other guy. I'm just hot."

She continues, "But then that wrinkly, white-haired guy used me in his campaign ad, which I guess means I'm running for president. So thanks for the endorsement white-haired dude."

"I want America to know that I'm, like, totally ready to lead," she says, before launching into a brief discussion of energy policy, and suggests a hybrid of McCain's offshore oil drilling plan and Obama's incentives for new energy technology.

"Energy crisis solved! I'll see you at the debates," she says.

Minnesota Gov. Tim Pawlenty, touted as a possible running mate for McCain, told reporters at the National Press Club on Wednesday, "I have to give Miss Hilton credit."

"She came back with a pretty funny response that will probably elevate her celebrity status," Pawlenty said.

Hilton's mother, who with her husband donated $4,600 to McCain's campaign earlier in the year, has said McCain's ad is "a complete waste of the country's time and attention at the very moment when millions of people are losing their homes and their jobs."
