It was an epic battle of open letters and violent tweets, but it's all over now: The Osbournes have buried the hatchet with Lady Gaga, ending one of rock's weirder public feuds.

It all went down at MusiCares' Grammy Week event, where Jack Osbourne was acting as a correspondent for Fuse, and where Jack's parents Sharon and Ozzy happened to be strolling the red carpet within shouting distance of Gaga.

Fortunately, no one did any shouting here. Sharon started the conversation, telling Gaga, "I’m determined we’re going to bury the hatchet"; Gaga responded that, in her opinion, their war ended when she and Sharon embraced on the U.K. edition of 'The X Factor' in 2013. "I’m a really huge fan of you guys for a very long time, so it’s totally water under the bridge," she told the Osbournes -- and then she proved it by sharing a story about the days when she and a friend did a Black Sabbath strip routine.

Those who love watching Sharon duke it out needn't worry, however; as we previously reported, she quickly picked up a new feud to replace her expired beef with Lady Gaga, causing a scene at Clive Davis' annual pre-Grammy gala by getting into a food fight with Sara Bareilles' (now former) manager.
