Kelly Osbourne was once so drunk she splashed out on diamond encrusted Chanel J12 watch.

The 'Fashion Police' star - who has previously been in rehab - rarely drinks anymore but admitted her drinking was once so out of control she used to go on huge spending sprees while under the influence.

She said: ''My biggest splurge purchase ever was a diamond encrusted Chanel J12 watch. I woke up wondering who gave me such a beautiful gift, then I found the receipt in my purse. Then I found the receipt in my purse. A good lesson learned in my former life, Don't drink and shop.''

Kelly also revealed Sir Elton John once gave her a beautiful Hermes travel collection bag set but a former friend stole part of it.

She told America's In Touch magazine: ''Elton John gave me a silver, leather Hermes weekend travel collection bag set. It's one of a kind, but I only have two of the pieces left because a certain young starlet stole it from my house.''
