Kelly Osbourne told her arch-nemesis Lady Gaga to "eat my sh*t" when the singer tried to make amends by presenting her mother Sharon Osbourne with a birthday cake for Kelly.
The 'Fashion Police' star was fuming when the singer tried to make amends with her mother Sharon Osbourne following her performance on 'The X Factor' UK on Sunday night (27.10.13) by presenting her with a birthday cake for Kelly, and immediately took to Twitter to inform Gaga she could "eat my sh*t".
The Osbournes have been locked in a bitter feud with Gaga for months, with Sharon branding the 'Applause' hitmaker - whose Born This Way Foundation campaigns against bullying - a "publicity-seeking hypocrite" for letting her fans send threatening messages to her daughter Kelly after she criticised Gaga's 2012 Grammy Awards outfit.
It seems 'X Factor' judge Sharon was willing to put the feud behind them as the former enemies hugged it out and posed together with a photo of a birthday cake Gaga had brought for Kelly. They had also met at London's G-A-Y nightclub on Saturday night (26.10.13).
However, outspoken Kelly - who was watching from the US - was far from impressed and took to Twitter to tell her nemesis what she really thought of her peacemaking skills.
In an increasingly angry series of tweets, she ranted: "Not to be ungrateful but why would you send me a birthday cake via my MOTHER in a country half the would away? #JustSendItToME #LoveNotWar
"#EatMyShit #Hypocrisy / #StefaniStopIt! / You are so far behind you think you are first! / I live for a #Cause not for the #Applause!!!!!!!
"I like desert, but i prefer the truth... it's sweeter / 'Let them eat cake' #MarieAntoinette (sic)".
While Gaga didn't respond to Kelly's messages, she warned her fans - who she calls her Little Monsters - to keep their opinions to themselves.
She posted: "Monsters, please just focus on the positive of tonight's performance and do not send any hateful messages. I don't support it. #SpreadLove"
Sharon joined the feud after Kelly was inundated with abuse from Gaga's fans online. The showbiz matriarch also voiced her disdain for the star in her new autobiography, 'Unbreakable'.
