Kelly Osbourne wants to end public Twitter spat with Gaga

Kelly Osbourne wants to end her public Twitter feud with Lady Gaga "like adults".
The 'Fashion Police' host has reached out to the singer to apologise for acting "like a child" when the singer gave her mother Sharon Osbourne - who is a judge on the UK version of 'The X Factor' - a birthday cake to pass on to Kelly, who turned 29 on Sunday.
