Random Celebrity Twitter Feud of the Day: Kelly Osbourne vs. Dannii Minogue

Kelly Osbourne has been involved in Twitter feuds before (cough, Tila Tequila) but now she's got a bone to pick X-Factor judge and singer Dannii Minogue.

Dannii claimed fellow panelist Sharon Osbourne made her during her first night on the British talent show, which did not sit well with the outspoken Kelly.

"The best thing to happen to Dannii was my mother hated her she needs to shut her mouth and concenterate [sic] on motherhood!" Osbourne Tweeted.

Dannii Minogue and Kelly Osbourne are going Twit-to-Twit.

The younger Osbourne was peeved over Minogue's assertion in her memoir, My Story, that she was steamrolled by Sharon when two began working together.

Specifically, Minogue wrote that Sharon "demanded to know why I hadn't gone to the press to tell them what a nice person [she] was," causing her to cry.

But Kelly calls BS on that.

"I will be the first one to admit that my mother did not play her cards right when came to dannii but trust me when i say dannii is the devil," Kelly tweeted.

And there's more:

• "dannii you are so lucky i respect Simon enough to not tell the truth about what happened. wa wa wa you poor middle aged victum [sic]"
• "to the 12 dannii fans out there i ask you this question what would you do if someone wrote a book of lies about your mother?"
• "i think you all forget i was there i saw everything and if my mum was the "bully" why was she the one the left the show?"
• "sorry i have just had to deal with this bulls--t 4 years and i have kept my mouth shut but i am sick of her lies enough is enough"

Harsh stuff. Anyone viewers out there any input on it? Dannii Minogue has yet to respond, via press release, public statement or Tweet.
