Kelly Osbourne broke down in tears on a new chat show called The Talk as she revealed one of her biggest fears.

Obsourne, 26, admitted that she struggles from serious anxiety that she might get cancer and frequently visits her doctor for health checks and regular injections of the vitamin B12.

The ‘Papa Don’t Preach’ singer’s concerns stem from her mother’s, Sharon Osbourne, diagnosis with colon cancer back in 2002, from which she is now cleared.

She said, “People automatically assume that once you're in the public eye, everything's amazing and your life has always been amazing because you're in Hollywood, but you know, my mum has had the hardest life you could ever imagine”.
