Utter nonsense, she has lived in Spain since the attack.
There are currently rumours doing the rounds on Twitter and several other places that she has died. These have not been confirmed by any official sources as yet and there are wildly conflicting reports, plus this would not be the first time nonsense stories have been circulated about her, if it turns out that this is such.
So please exercise some restraint until everyone knows for sure what has happened out of respect for Natalie and her friends and family.
