The ‘Fashion Police’ presenter and the singer have fired their fare share of twitter insults at each other over the past year but the hatchet seems to have finally been buried. Party host Elton John seems to have had a hand at reuniting the pair, perhaps teaching them that sorry doesn't have to be the hardest word when the two ladies bumped into each other at the last night.

Poking fun at their rivalry, Kelly instagramed a picure which showed her pretending to choke Gaga under the caption 'peace at last', as Elton looked on. The long running feud started back in 2009 when Kelly called the singer a ‘buttaface’ over twitter. Gaga responded by criticising Kelly’s involvement in E! show, ‘Fashion Police’, which the singer said “is rooted in criticism, judgment, and rating people's beauty against one another.” The feud continued and a one point involved Kelly’s mother Sharon, who wrote an open letter to Gaga saying, ‘“Stop wearing fur, stop looking for publicity, and stop using your fans to belittle not just Kelly but an endless stream of celebrities.”

Gaga had attempted a reconciliation when she sent a birthday cake intend for Kelly to Sharon, but Kelly was less than grateful tweeting “why would you send me a birthday cake via my MOTHER in a country half the would away? #JustSendItToME #LoveNotWar.”

However things looked to be settling down in the feud last month when Gaga was seen hugging matriarch Sharon at a MusicCares event with Osbourne saying she was determined to bury the hatchet.

Both girls had an Oscar night filled with parties and costume changes. Kelly hosted E!’s coverage of the red carpet, originally in a Badgley Mischka gown which she later found out she couldn't do stairs in. She then changed to a black embellished dress as she partied with her parents at Elton John’s bash.

Not to be outdone Gaga wore an elegant pink Versace gown at the beginning of the night, before changing into a white cut out dress for the Vanity Fair party.
