Paris Hilton has made a spoof advertisement in response to a jibe by US presidential hopeful John McCain.

A commercial suggested Mr McCain's Democratic rival, Barack Obama, was no more than a lightweight celebrity, like Hilton or Britney Spears.

But in a spoof recording placed on the comedy website Funny or Die, Hilton referred to Mr McCain as "that wrinkly, white-haired guy".

She claimed being used in his ad meant she was now "running for president".

'Complete waste'

Reclining on a chair in a swimming costume and gold stilettos, she said: "Thanks for the endorsement, white-haired dude.

"I want America to know that I'm, like, totally ready to lead."

At the beginning of the star's film, an announcer called Mr 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".

Hilton's spoof also intersperses images of Mr McCain and Yoda from Star Wars and the cast of TV show The Golden Girls.

The star, who spent 23 days in a Los Angeles prison for breaching probation on a driving ban last year, then discusses her energy "policy".

The 27-year-old suggested a hybrid of Mr McCain's offshore oil-drilling plan and Mr Obama's incentives for new energy technology.

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

A spokesman for Mr McCain's campaign, Tucker Bounds, said: "Paris Hilton might not be as big a celebrity as Barack Obama, but she obviously has a better energy plan."

Hilton's mother Kathy, who - along with her husband - donated $4,600 (£2,353) to Mr McCain's campaign earlier in the year, has commented on the Republican advert.

This was "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", she said.
