Kelly Osbourne will never work with music mogul Simon Cowell - because of his huge ego.
The reality TV star's mother Sharon worked with Cowell on British TV talent contest The X Factor, but quit earlier this year (08).
And Osbourne understands why her mother could no longer work with the British music svengali.
She says, "I don't know how he gets his head through the holes in his T-shirts because they're really tight.
"You don't have enough money, in this world, to pay me to work with Simon Cowell."
Osbourne admitted she almost boycotted the X Factor, but changed her mind after learning Cheryl Cole had replaced rock matriarch Sharon.
She adds, "Seriously, I'm the biggest Girls Aloud fan, and that's the only reason why I'd ever watch it again."
