Robbie WilliamsRobbie WilliamsFancy getting Robbie Williams to sing at your birthday party? You can - if you've got a million quid to spare.

That's how much the chart-topping singer pocketed to perform at businessman Michael Spencer's 50th birthday bash over the weekend.

Robbie performed 15 songs, including Let Me Entertain You and Angels, at the party in the South of France - an average of £70,000 per song.

And, according to the Daily Mail, he's already given his seven figure fee to charity.

"It was an incredible party," one guest told the paper.

"It had everything money can buy - and then some. When Robbie came on there was a huge cheer.

"People could not believe that he was there playing to them in such an intimate venue."

The 300 guests were also treated to a set from seventies hitmakers Sister Sledge.
