Sharon Osbourne And Simon Cowell: It's War!

Sharon Osbourne is digging her claws into former colleague Simon Cowell by commenting on his recent break up.

The former X-Factor judge - who is rumoured to have fallen out with both Simon and Dannii Minogue - made it apparent that there is no love lost between the pair.

She told the Mirror, "He's a t****r, that's the truth."

Ozzy's wife added that she thought Simon "deserved" to be dumped by his partner Terri Seymour.

Sharon's replacement, Cheryl Cole is also rumoured to be having cat fights with Dannii.
