Cannes: High Heels and Heidi Klum at amfAR

Last night was the biggest charity event on the Cannes Calendar and I had bagged one of the most sought after invitations in town. I was off to the amfAR dinner and party. The annual Cinema Against AIDS ball attracts all the A-listers and is a fantastic event for a great cause. The Foundation for AIDS Research is one of the world's leading organisations dedicated to HIV research, prevention, treatment and education.

Locals and tourists line the streets on the route to Hotel du Cap-Eden-Roc waving at the cars in the hope of catching a glimpse of the stars. I'm not sure who they thought I was but I was polite and waved back!

I found myself on one of the biggest red carpets I've seen... it was massive. As I tried to run down it without drawing attention to myself I was in for a major fail. Somehow I was suddenly caught in the middle of Kim Kardashian and Janet Jackson. That was a celebrity sandwich and a half. Kim looked amazing with flawless skin. Janet - well she looked like she needed persuading to pose for her pics. Luckily her posse was on hand to reassure her she looked great. I thought she looked skinny!

Once inside we were ushered to our tables as Karl Lagerfeld, Antonio Banderas, Kylie Minogue, Berenice Bejo, Harvey Weinstein, Joshua Jackson and Diane Kruger took their seats around me. If you like people watching you'd have been in your element.

An auction took place over dinner. The whoops came during Lot 3 when a collection of 1911 Vintage Moet & Chandon champagne sold for 150,000 euros! That's one expensive hangover. Other highlights included Harvey Weinstein and Karl Lagerfeld teaming up to offer someone the chance to star in a short film produced and directed by them. One hopeless and rich romantic splashed out 350,000 euros for the gift for his girlfriend. Wonder if he has a single mate?

Entertainment came in the form of Jessie J, Aloe Black and Fun performing their hit We Are Young.

And that was just the first course of fun. I followed Gerard Butler over to the after-party but it took me an hour to get near him for the hordes of women who were literally throwing themselves at him. I've never been in a room with so many beautiful people. He was gorgeous and down to earth and made time for everyone. He definitely hasn't forgotten his Scottish roots or let Hollywood go to his head.

By 3am my feet were killing and it was time to call it a day as Macy Gray and The Paperboy crew continued to live it up on the dancefloor. Obviously, I tried to say goodbye. As I stumbled out of the do I bumped into Heidi Klum and found out we were sisters with blisters as we whipped off our heels and made the journey home barefoot!
