Jack Osbourne has rubbished reports he underwent liposuction to achieve his toned new look, because only vain people resort to plastic surgery.

The reality TV star recently shed 32 kilograms (70 pounds) thanks to a strict exercise regime and diet - and would consider surgery as a last resort as he refuses to become image-obsessed.

Osbourne's mother SHARON has spent $216,000 (GBP120,000) on surgery including liposuction and breast implants, but he sees no need to have work done on himself.

He says, "I don't think so. I've read stuff saying I've had a nose job and lipo and that I had a nose Brad Pitt would envy.

"I don't think I'm that kind of person who would have it. I'm just not that vain."
