'Fashion Police' co-host Kelly Osbourne has reached out to pop sensation Lady Gaga after publicly rejecting the birthday cake she gave her mother over the weekend. 

During Gaga's performance on 'The X Factor', she gave Sharon Osbourne a birthday cake peace offering (pictured below) for Kelly. Upon hearing about it, Kelly posted a series of messages on Twitter slamming Gaga for trying to look like the better person:

"Not to be ungrateful but why would you send me a birthday cake via my MOTHER in a country half the would away? #JustSendItToME #LoveNotWar. #EatMyShit #Hypocrisy."

It appears that Kelly may have had a change of heart because earlier this morning (October 29), she tweeted to Gaga and apologised for her behaviour and comments: "@Ladygaga 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."
