Pete Doherty was devastated when he reached his 30th birthday in April, and got so drunk at his party he began to think he couldn't go on.
He explained: "I had this bash in Paris and it was an absolute disgrace. I just made a bit of an idiot out of myself. We had a right old knees-up. I don't even know exactly what happened but I ended up trying to throw myself off the top of the hotel. I wasn't happy at all about being 30."
Doherty eventually decided to take his frustrations out on the catering staff, much to the dismay of his friends.
He revealed to Britain's Elle magazine: "I don't normally drink that heavily. But I went through a bottle of vodka. They presented me with this cake and I pushed it in the chef's face who'd just made it for me.
"Then the chef and the security guards were chasing me around. I think I escaped unscathed. It was hilarious. I had a great night."
