Kelly Osbourne has hit out at claims that suggest she was drinking heavily at a Golden Globes afterparty last weekend. 

The singer and television presenter, who turned her back on drink and drugs three years ago, was disgusted to see that RadarOnline.com had reported that she spent Sunday, January 15 boozing at celebrity-studded soirées and took to her official Twitter account to clear up the rumours:

"Thats funny radar because i was not even at any of the after parties i was working!!!! @radar_online please stop writing bullshit about me i did not even go to any golden globe parties i was working!"

Last night, January 19, Osbourne added: "My room mate & i are having a proper laugh about all this B,S press he goes 'i wish you were that fun U never do anything but work old lady."

"If I want to have a drink them I'm going to have a drink Im 27 years old! Was their story true? NO! is it anyone's business NO?#GiveMeABreak!"
