Kelly Osbourne: I’m not pregnant!

Kelly Osbourne is incensed people thought she was sporting a baby bump at the Grammys.

The 30-year-old Fashion Police panellist hosted the 57th Annual Grammy Awards E! red carpet special with Giuliana Rancic and Brad Goreski.

She donned a long, figure hugging black and white gown with a train designed by Christian Siriano to the lavish ceremony.

Some fans took to Twitter speculating as to whether Kelly may be pregnant because of the way her dress fit around the womb area, and she addressed those inquiries promptly.

"NO IM NOT PREGNANT YOU F***ERS!" she tweeted.

Kelly took the time to release even more information about her mental state on the Grammys red carpet.

She made it clear looking fabulous at the event in her high-fashion gown felt very uncomfortable at times.

"I have a back brace on AND I REALLY NEED TO TAKE A SH*T! #SuckIt," she wrote on the micro-blog.

Kelly's Fashion Police co-host Joan Rivers died at the age of 81 last September and on Sunday the comedic legend received a posthumous Grammy for her spoken word album, Diary of a Mad Diva.

And Kelly couldn't be more happy about her late friend's accolade.

"Guess what? Joan won! How amazing, I'm so happy!" she gushed on the E! red carpet special with co-host Ross Mathews by her side. "Best Comedic Album, we are so proud and honoured thank you very much the Grammys."

Although Kelly experienced many ups and downs at the Grammys Sunday night, she and Ross still managed to have some fun.
"When we are not live helloross & myself have the best time messing around with our set props!" she wrote on Twitter.
