Kelly Osbourne's expensive chat

Kelly Osbourne ran up a £2,500 phone bill.

The presenter - whose parents are Black Sabbath rocker Ozzy and 'America's Got Talent' judge Sharon Osbourne - was astonished when she got her recent statement as she thought she had been careful to curb her mobile phone use while in America competing in reality TV show 'Dancing With The Stars'.

She said: "Oh, my God, I've just had my most expensive phone bill. Do not have an iPhone if you travel because it seems like they charge you every single time you even press a button on your applications. My bill was £2,500. And I was making a conscious effort not to use it so much."

However, Kelly - who is engaged to model Luke Worrall - didn't run up the bill speaking to Ozzy, though she admits her close bond with Sharon was a contributing factor.

She added to Britain's Cosmopolitan magazine: "My dad is really bad with his phone. The conversation only lasts about three seconds but it's just nice to speak to him.

"I speak to my mum about 20 times a day. I find any excuse to call her as I just like talking to her."
