Kelly Osbourne fractures hand: 'I'm world's most accident-prone person'

Kelly Osbourne fractured her left hand in three places over the weekend.

Ozzy Osbourne and Sharon Osbourne's daughter revealed on Twitter that she suffered the "excruciating" injury while falling out of bed.

"I must be the most accident prone/stupid person in the world[.] I fell out my bed while sleeping last night & fractured my hand in 3 places! I'm staying in a hotel and the bed is so tall I must have dropped about 4 1/2 feet," she tweeted.

Kelly eventually had her injured hand wrapped in a cast and is now under the care of her mum Sharon.

"It's my left hand & I'm left handed so my mum has to brush my hair & cut my food 4 me I feel like a baby again. Of course my mum is loving it! The worst part is I permanently look like I'm giving everyone the thumbs up because of the way it's casted! I look like such a t**t," the Fashion Police star joked.

In November, Kelly was briefly hospitalised when she suffered a head injury.

Last week, Kelly and friend Miley Cyrus urged Twitter to remove cyber bullies after receiving a series of disturbing messages.
