Sharon Osbourne is so ''happy'' that the 'Fashion Police' host has buried the hatchet with her long-time rival after recently posting a furious rant on Twitter about the 'Applause' hitmaker for presenting her mother with a birthday cake to mark Kelly's 29th birthday.
Sharon told EOnline.com: ''You know what, life is way too short. And Gaga was so gracious and extended herself to Kelly and I'm glad that Kelly came around because you know what, it's juvenile. And thank god it's over.''
Kelly apologised several times last week for slamming Gaga for sending her a cake via Sharon after performing on 'The X Factor'.
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 told 'Hello Ross': ''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.
