Kelly Osbourne rejects Gaga`s birthday cake

London: 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’. 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 an 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".
