Paris Hilton: "I'm Not Cheating On Benji Madden" 10/21/08

Paris Hilton has celebrated her eight-month anniversary with rocker Benji Madden by phoning home from London to clear up royal romantic rumors.

The socialite called in to pal Ryan Seacrest's radio show in Los Angeles on Tuesday morning (21Oct08) to address British tabloid reports she has been caught flirting with British Princes William and Harry after meeting the royal brothers at the London Hilton. Hilton told Seacrest she has met with William and Harry - but there's nothing to the rumors, and she's not texting love notes to either of them.

She said, "They're very nice boys, very down to earth and sweet but there's nothing romantic going on at all. They just came up and said hello. There's no texting going on; I'm reading that I invited them to Las Vegas to a club - that never happened."

"I have a boyfriend, it's an eight month anniversary today. I would never say that in a million years and it just annoys me that particularly the media out in the UK, they will not only make up stories, they'll also go as far to make up quotes that I supposedly said. "William was really nice... Harry was with his girlfriend, Chelsea, who was so stunning, beautiful and sweet... They were just very friendly, they weren't flirting at all."

"I'm taken, I don't put it out that I'm single. Before, I wasn't in love... I would never hurt him (Madden)."

Hilton admits she's also upset with reports Madonna's estranged husband Guy Ritchie treated the socialite to a tour of his Sherlock Holmes set - and offered her a role in the new film. She added, "I didn't even know there was a Sherlock Holmes movie... It's so ridiculous. "I did meet him (Ritchie) at his pub (The Punch Bowl) and he was very nice."

Meanwhile, Hilton, who is in London shooting a British version of her reality show My BFF is planning a very romantic weekend with Madden, who flies to the U.K. weekly to hang out with his girlfriend.

She says, "There's a big carnival fair here so we're gonna go on some rides and then go for a nice dinner and hang out in the room."

As an eight month anniversary gift, Madden had roses and caviar delivered to Hilton's hotel room this morning.
