KELLY OSBOURNE is refusing to back down in her feud with LADY GAGA despite the pop star commissioning a cake in celebration of her 29th birthday.
The pair has been embroiled in a war of words since Osbourne was bullied by some of Gaga's devoted fans, prompting the Bad Romance singer to write an online note to her pal in January (13) criticising her role on Fashion Police.
The row was further fueled by Kelly's mother Sharon Osbourne, who lashed out at Gaga and branded her an "attention seeker".
The singer performed on the U.K. version of The X Factor on Sunday night (27Oct13), and received a standing ovation from Sharon, who sits as a judge on the show. The rock manager revealed they had sorted out their differences backstage.
Gaga presented a cake to Sharon in honor of her daughter, who celebrated her birthday on Sunday (27Oct13), but the reality TV star has snubbed the peace offering in a series of angry tweets.
She writes, "Not to be ungrateful but why would you send me a birthday cake via my MOTHER in a country half the would (sic) away? #JustSendItToME #LoveNotWar EatMyS**t #Hypocrisy.
"I like desert, but i prefer the truth... it's sweeter."
