Kelly Osbourne Tells Lady Gaga to 'Eat My S***' After Singer Sends Birthday Cake

Kelly Osbourne has lashed out at Lady Gaga because of cake, Us Weekly reported Monday.

Kelly turned 29 on Sunday and Lady Gaga offered her mother, Sharon Osbourne, a cake during her appearance on the U.K.'s X Factor. It was meant to be a peace offering since the two have been feuding for the past few months. Sharon appreciated Lady Gaga making the effort.

Blown away by Lady Gaga's performance and graciousness.

However, Kelly went on an expletive ridden Twitter rant. She accused the 27-year-old Applause singer of being insincere. She also belittled the efforts by ordering Lady Gaga to “eat shit”.

Lady Gaga did not respond to the negative feedback. She reiterated that the cake was meant to mend the thaw in their relationship. Earlier in the year, the two exchanged open letters. Kelly had accused Lady Gaga of being a hypocrite who championed against bullying but engaged in it through her fans. Lady Gaga denied the charge and on Sunday directed her fans to seek the higher ground.

Monsters, please just focus on the positive of tonight's performance and do not send any hateful messages. I don't support it. #SpreadLove — Lady Gaga (@ladygaga) October 27, 2013
