The former Libertines rocker was in a turbulent relationship with the supermodel from January 2005 to July 2007 and when they finally separated for good, Kate angrily ruined his things. However, she couldn`t bring herself to smash the model animals and Pete is considering sending them to her and her new husband Jamie Hince as a belated wedding present. In an interview with The Independent newspaper, he said: "Kate used to collect elephants, so I`d buy them for her wherever I went. When we split up she destroyed all my stuff, but she didn`t destroy my elephants. Because I couldn`t get over her for a while I just kept buying elephants and now I`ve got a huge elephant collection for sale. I might post them anonymously to her as a wedding present." The `Can`t Stand Me Now` singer - who has started a new career as an artist - admits there are a lot of things he regrets about his relationship with Kate and accepts he was "unhinged" during their romance because of the amount of drugs he was taking. But Pete - who was hooked on crack cocaine and heroin - did not consider getting clean for the catwalk beauty because she knew he was an addict when she started dating him. Recalling his life with Kate - who was videoed allegedly snorting cocaine in a recording studio with Pete during their relationship - he said: "I was a bit unhinged at that time. The drugs. The thing is, she knew from day one when we began our relationship that I was using very heavily. She knew that. So, you can`t suddenly turn around and say, `You`ve got to stop all that.` I do have regrets about Kate ... but I`d only talk to a highly skilled doctor about them, with large amounts of morphine and a hypnotherapist. And a small monkey."
