KELLY OSBOURNE REJECTS LADY GAGA'S PEACE OFFERING, TELLS SINGER "EAT MY SH*T"

The Kelly Osbourne/Lady Gaga hatchet is anything but buried! Despite Sharon Osbourne and Lady Gaga publicly kissing and making up on the UK X Factor on Sunday night,
the bold and brash Kelly was having none of it.

On the show on Sunday night, the 27-year-old singer presented Kelly, who has been notoriously feuding with Gaga for years, a birthday cake for the violet-haired personality's 29th birthday. Apparently, the bday girl was no mood to take the olive branch and retaliated by posting a pic of the cake on her Twitter with the caption, "#Eat my sh*t #Hypocrisy."

This was definitely not a successful peace offering! Kelly also wrote, "Not be ungrateful but why would you send me a birthday cake via my MOTHER in a world half the would away #JustSendItToME #LoveNotWar." Gotta hand it to Kelly -- she makes some good points.

And while we think it's good Gaga is trying to make peace -- but it is definitely an odd way to do it. The diva wore goes all the way back to 2009, after Kelly criticized Gaga for skipping her at the Grammy red carpet, which eventually caused a backlash from Little Monsters on Twitter.

Kelly further angered Gaga's rabid fans when the Fashion Police host said she thought Gaga was pregnant after wearing a burkha style outfit.

Ozzy's offspring went off on Gaga's fans saying that the singer preys on them, "I know the truth. Your bells and whistles mean nothing to me. You're feeding on the freaks and geeks to further your career?"

Gaga hit back saying Kelly should, "defend others who are bullied for their image." Kelly's strong-willed mom defended her daughter after fans spewed hate at Kelly, and wrote a strongly worded open letter to the popstar, who is an anti-bullying advocate.

In the letter, the 61-year-old Brit called Gaga a bully and "nothing more than a publicity seeking hypocrite and attention seeker." The X Factor judge even went so far as to chronicle the feud in detail in her new autobiography Unbreakable, released on October 20. Clearly the "Born This Way" singer came in to Sunday night's taping waving the white flag.

Reportedly, the Mother Monster and Sharon met up privately before the live show and made peace. The two even hugged it onstage, during the show.
