Socialite Kim Kardashian has laughed off rumors she's dating Portuguese soccer superstar Cristiano Ronaldo after they were alleged to have enjoyed an intimate lunch together in Miami, Florida.

The Keeping Up With The Kardashians star split from her on/off boyfriend, Reggie Bush, last month and was said to be moving on with the sporting stud following a date at La Dorada restaurant. A source told Us Weekly magazine, "They met before, in Los Angeles. She hasn't been single in years, so she's having fun."
 
However, Kardashian is baffled by the reports, insisting there is nothing romantic between the pair - and she's keen to weed out the 'insiders' who claim to know all about her private life.
 
Speaking on an Australian radio show, she says, "According to the US media, I'm kissing a lot of people. Every time if you are just in the same place as someone they always say you are dating them so at this point I've given up."

"Who is the source? I'd love to know, I want to work for a blog and find out who these sources are. I think I'm such a relationship kind of girl for years, I think it would be really refreshing and I'm having a good time being single."
