Paris Hilton and Cy Waits `re-evaluating their relationship`

The couple is said to be re-evaluating their relationship because Cy believes that The World According To Paris delved too deeply into their private lives.

A source told E! News, 'Paris loves and respects Cy very much. He has been through a lot with her. But sometimes it's hard on the relationship because he's not used to this lifestyle, the media and being on a show.

'Cy is very upset with The World According To Paris. He felt that way too much of their private life was shown. When he signed on to do the show, he had no idea the cameras would be so invasive.'

Another strain on their one-year romance seems to be distance, with Paris traveling for work while Cy is based in Las Vegas, and the fact that Paris is reluctant to say that he is 'the one'.

'Cy has a daughter and he's very protective about keeping her out of the media and wanting her to lead a normal life,' said a second insider.

'Sometimes he feels like Paris isn't ready to take the next step. They both love each other very much and are deciding what to do now.'
