Following a Twitter rant aimed towards Lady Gaga, Kelly Osbourne is apologizing and asking the ARTPOP singer to make peace once and for all.

The Fashion Police star and daughter of Ozzy and Sharon Osbourne tweeted Gaga and asked her to call her so they can hash it out like adults.

The gesture comes after Osbourne’s explosive rant, in which she told Gaga to “eat my sh-t” when she sent her a birthday cake through her mom, Sharon, when appearing on X Factor.

“Not to be ungrateful but why would you send me a birthday cake via my MOTHER in a country half the would away? #JustSendItToME #LoveNotWar,” Osbourne wrote, to which Gaga replied, “I didn't know it was your B-day until this afternoon. Meant as a peace offering. Happy Birthday.”

Their feud started last year when Gaga penned an open letter to Osbourne telling her that her work on her E! show was “rooted in criticism, judgment, and rating people's beauty against one another.”
