Osbourne, Hopkins in online row
Kelly Osbourne has launched a scathing attack on Katie Hopkins after she took a pop at her mum Sharon Osbourne.
Former Apprentice star Katie had a swipe at X Factor judge Sharon in her Best magazine column, referring to her being a fan of plastic surgery.
She wrote: "Sharon reckons her time on the panel may be up. Either way, if she is going to look this good next year she will need to bulk buy plastic."
Discussing Sharon's emotional reaction to Sam Bailey's last performance on The X Factor, Katie said: "She decided to earn it by collapsing in mild hysteria on the desk. Tears came out from behind her ears."
Fashion Police star Kelly then hit back, tweeting: "U R a hypocritical vile human that is addicted 2 attention U R so insignificant! Don't you ever talk about my mother again!"
Katie replied: "Just like Peaches and Jesus, Kelly has done well due to a famous parent."
Kelly, 29, later continued: "I know that what I am about to say is unbecoming of a lady & Im sorry to say this but I can't lie you are a massive #C***."
Katie, 38, wrote back: "No problem Kel. No one ever mistook you for a lady sweetie pie.@KellyOsbourne."
