Kelly Osbourne Tells Lady Gaga 'Eat My S--t,' Calls Her A Hypocrite On Instagram

Kelly Osbroune slammed Lady Gaga this weekend, telling the singer to "eat my s--t" and calling her a hypocrite.

The harsh words came after Lady Gaga appeared on UK's "The X Factor" Sunday (Oct. 27) and gave judge Sharon Osbourne a cake for Kelly's 29th birthday, which she celebrated this weekend, notes Just Jared. Apparently, Gaga's gesture was lost on Kelly, who took to social media to blast the "Applause" singer.

She also posted a photo of the cake to Instagram and captioned it with "#EatMyS**t" and "#Hypocrisy."

The 27-year-old superstar didn't seem to be looking for a fight, though. She tweeted at the "Fashion Police" host, saying, "I didn't know it was your B-day until this afternoon. Meant as a peace offering. Happy Birthday."

Gaga's feud with the Osbournes dates back years. In 2009, Kelly called Gaga a "butterface" and last year said that Gaga's fans have been telling her to go kill herself. When Gaga responded in a blog post earlier this year, saying Kelly needs to take accountability because she is critical of people on her E! show, Sharon called Gaga a "bully" and a "publicly seeking hypocrite and an attention seeker."

On Sunday, however, Sharon and Gaga seemed to bury the hatchet when they embraced on "The X Factor." The 61-year-old later tweeted about her change of heart.
