Kelly Osbourne Falls Out Of Bed - Breaks Hand

I'm not sure if we are getting the entire story from Kelly Osbourne. She Tweeted that she fell out of bed and broke her hand in three places. When is the last time you fell out of bed during the night? I'm talking about sleeping, not having sex or playing Wii. I bet you don't even remember because it has not happened since you were a kid. So, what do we think really happened? I would say she fell off the wagon, but when I pass out drunk, I don't even move so doubt I would fall off the bed. Kelly is accident prone because last month she suffered a head injury and was knocked unconscious.
