Paris Hilton has taken to twitter to deny rumours she has split with boyfriend Doug Reinhardt saying the claims are "100 per cent false."

Her denial follows reports that Doug's younger sister was offered her own reality TV show. US baseball player Doug was apparently invited to be a producer as long as Paris featured in some episodes.

But it was claimed the 29-year-old was not keen and without her involvement the show would not go ahead, reportedly making Paris question Doug's intentions.

The socialite was then spotted in Las Vegas, partying with her sister Nikki and Kim Kardashian's ex-boyfriend Reggie Bush, leading some to assume that she was now enjoying the single life.

However Paris has tweeted: "Can't a girl have a night out in Las Vegas with her sister without false stories being posted. That story is a ridiculous lie. 100 per cent false."
