Reality show star Kelly Osbourne did not accept the peace initiative taken by singer Lady Gaga.
Gaga clicked a picture with Kelly's mother Sharon Osbourne while on the sets of singing show "The X Factor" with a cake in her hand that said "Happy Birthday Kelly".
But the actress posted the same picture on her Twitter account and captioned it as "Eat my s***", reports dailymail.co.uk.
Kelly and Gaga have been publicly quarreling since 2009, but last year things got out of control when the singer's fans, waged an online campaign of hatred and abuse against the actress.
Sharon also did not take too kindly to it and released a open letter to Gaga criticising the anti-bullying advocate and calling her a bully and "nothing more than a publicity seeking hypocrite and attention seeker".
