I still can't believe that Natasha Richardson is dead - and as the result of such an innocuous incident. It wasn't even like she was on a black slope or anything. She was just trying to get the hang of things on the ski resort's nursery slopes. It's just too sad for words.

I know it's said so often it's become a cliche, but my heart really does go out to her family and young sons. Her husband Liam Neeson looked absolutely devastated as he bravely tried to raise a smile for photographers waiting outside the couple's New York apartment as he returned from the hospital after the family had said their goodbyes. I can't even begin to imagine their heartbreak.

Celebrities so often seem to lead charmed lives. An incident like this just goes to show that they're vulnerable to exactly the same unexpected twists of fate as the rest of us, though. Sometimes you wish they weren't. It's bad enough to lose someone you love, but having to put a brave face on things as the world watches how you cope must be incredibly hard.

What with Jade Goody and now Natasha there seems to have been an awful lot of sadness around in the world of celebrity of late. I guess these things go in cycles, but at the moment I'm finding my personal celebrity radar dominated by Jade's brave struggle, and the heartbreak of Natasha's family.
