Paris Hilton has hit out at claims of a relationship with Real Madrid's world record signing Cristiano Ronaldo.

The hotel heiress ended her six-month romance with Doug Reinhardt earlier this month and shortly after news of the split broke, she was photographed getting close to Ronaldo in a Los Angeles nightclub.

But Paris ranted on twitter.com: "I'm really sick of reporters not only making up stories, but also inventing their own quotes that I never even said. It's ridiculous! They have no credibility. They make up vicious stories, and even though they are so far from the truth, it's still hurtful.

"They even invent relationships, if I even talk to a guy as a friend, they blow it so out of proportion and act like we are dating. So lame.

"Sorry for the venting, I'm just sick of all these stupid rumors. I'm trying to focus on my life and work and don't need the extra stress.

"Plus, I want you all to know the truth. Don't believe what you read, about 90 percent of it is pure fiction."

Paris' comments come after a source was quoted in the Daily Star that she was unimpressed by Ronaldo's antics.
