Sharon Osbourne has had porn sent to her phone by a stranger.

The TV star's daughter Kelly has revealed her mother contacted her in a panic after she opened up some messages and was unexpectedly presented with X-rated material.

Kelly wrote on her twitter page: "My mum just told me the funniest story. someone thinks they are texting a friend named sam but they are accidentally texting my mum porn!

"My mum is like 'i dont want anyone thinking i like looking at dirty horrible things like that!' she is freaking out its so funny!"

Although Sharon doesn't want to have porn sent to her cell phone she has been using her handheld much more in recent weeks, ever since her husband Ozzy finally learnt how to send text messages.

The 'Talk' host revealed on her twitter page: "So happy Ozzy has learnt how to text me so now we're talking all day long. I love it."
