It appears as though the feud between Kelly Osbourne and Lady Gaga may be over…for now.  The reality star apologized to Gaga for attacking her via Twitter a few days ago.

Just to recap: Kelly, Gaga and Kelly's mom Sharon were in a feud because Kelly and Sharon were upset that Gaga wouldn't tell her fans to stop making death threats against Kelly.  This past weekend, Gaga saw Sharon at the U.K. version of The X Factor and gave Sharon a birthday cake to give to Kelly.  Kelly responded by going off on Gaga, accusing her of hypocrisy, and telling her to "eat my s**t."  Gaga said the cake was a "peace offering."

But on Monday night, Kelly posted an apology, tweeting to Gaga, "I acted like a child last night. Just not into publicity stunts call me & we will end this like adults I dont want 2 fight anymore."

So far, Gaga hasn't responded via Twitter, but perhaps she's called Kelly to bury the hatchet.  Stay tuned.
