Cowell 'not impressed by Twitter popularity'

Simon Cowell has admitted that he does not understand the fascination with online blogging service Twitter.

Speaking to Extra, the American Idol and X Factor judge revealed that he is baffled by the sudden popularity of the social networking site.

"It's like phoning someone randomly, who's number you don't have, and talking to them. 'Hi, it's Simon, I went out with my family this weekend'," he said.

After being read a Twitter message from Idol host Ryan Seacrest, which said 'spent weekend with my fam', he replied: "What's sad is that he's having to use the Twitter language like he's 17. 'My fam' - how difficult is it to add on an 'ily'?"

Earlier, Cowell hinted that he might have to drop one of his reality shows after admitting that he is struggling to cope with his heavy workload.
