Kelly lays into "spineless" Dannii

Oh dear it looks like Kelly Osbourne is on the war path…again.

Just a few days after saying that she would never work with X Factor judge Simon Cowell, Kelly has laid into his fellow judge Dannii Minogue.

Kel's mum Sharon quit the X Factor before the current series and was replaced by Cheryl Cole.

Although the reasons for her decision were not revealed, it was no secret that Sharon and Dannii weren't exactly bessie mates.

Since Sharon's departure, Dannii has spoken openly about how much more comfortable and positive the atmosphere on set is.

But Kelly is not impressed with the Aussie pop star's comments.

She said: "Dannii is spineless really. She said nothing to my mum's face and even gave her an end-of-series gift.

"If she does not stop bad-mouthing her she will have me to contend with."

Look out Louis and Cheryl…it's only a matter of time before the Osbourne wrath targets you too.
