The 'Fashion Police' host and her mother Sharon had been engaged in a war of words for over a year, and though they agreed to call a truce late last year, they finally came face-to-face for the first time last night (02.03.14) at Sir Elton John's Annual AIDS Foundation Academy Awards Viewing Party in Hollywood.
As the host looked on, Kelly, 29, and Gaga, 27, shared a joke before posing for a joke picture which saw the presenter put her hands around the 'Applause' singer's throat.
Posting the photo onto Instagram, Kelly added the caption: ''Peace at last.''
In October, Gaga tried to make peace with her rival by sending a birthday cake via her mother Sharon after performing on 'The X Factor' in the UK.
However, Kelly rejected the gift, dismissing it as a publicity stunt, but later apologised for her ungrateful response.
She tweeted: ''@ladygaga I acted like a child last night. Just not into publicity stunts call me & we will end this like adults I don't want 2 fight anymore.''
She also said': ''I will just admit that I overreacted. I really did, because when you start to f**k with me and my mom, that's when I start to get a little bit... I saw it wrong. I saw it more as a publicity stunt than an olive branch. There's a lot of really huge misunderstandings on both sides of this ridiculous fight that doesn't even need to be happening.''
The Osbournes had been involved in a bitter feud with Gaga for months, with Sharon previously branding the eccentric singer - whose Born This Way Foundation campaigns against bullying - a ''publicity-seeking hypocrite'' for letting her fans send threatening messages to her Kelly after she blasted Gaga's 2012 Grammy Awards outfit.
