Paris Hilton and Benji Madden's duets are "happy and fun". The hotel heiress - who has been dating Good Charlotte rocker Benji since early this year - has been recording tracks with her musician beau, and says the songs reflect the couple's relationship.

She said: "The songs are just being mixed right now and should be done soon. I've got a recording studio at my house in Los Angeles and so we've been working there every night. It's been fun.

Our songs are just happy and fun dance music. It reflects what Benji and I are like together - happy and fun." Meanwhile, it has been reported Paris forced organisers of the Toronto International Film Festival to cancel two screenings of a new documentary about her.

 The blonde beauty demanded two of the three 'Paris, Not France' screenings were cancelled in a bid to make reviewers even more eager to see the movie.

Her representative Jason Moore said: "We wanted to create more buzz - create some hype. We felt the impact would be more extreme if we had just one screening."
