"Oh God, the hotel were not happy with that kind of press," he told heatworld. "I’m holed up in a hotel in Wembley for five days. I’ve got to behave myself. I can’t believe it. I was so drunk.

We're actually not sure which part is our favourite - the bit where Rylan (who has been put into a car by a security-type person) slowly starts creeping out of the opposite door on his hands and knees, OR when Lucy hauls him away over her actualy shoulder.
What do you think about Lucy and Rylan's night of fun - silly, or hilarious?
