London, Apr 2 : Media mogul Simon Cowell has lashed out at the celebrity Twitter craze, as he thinks that the concept of the social networking site is silly.

Cowell says that he just doesn't understand why people want to tell unknown people about themselves.

"Why would you want to talk to people like that?" the Daily Star quoted him as saying.

"It's like phoning someone randomly whose number you don't even have and talking to them," he added. (ANI)
