Dannii: (on her friendship with Robbie Williams) Here's an embarrassing story. When we were both at a bar in Berlin, this waiter walks past with a tray of drinks and drops it over my head. I'm in a silk dress, my hair is wet, my dress is wet, my shoes are wet and I have to walk through the lobby of the hotel to my room. Robbie comes over to me and asks if I'm OK. I just said: 'Please don't look at me or speak to me. I have to go now'.
