 The plan of a Spice Girls'reunion was first confirmed by Mel B in June 2005. She stated, "We'll get back together because we all want to. I know everyone is up for it. There is going to be a greatest hits album and we 've got loads of new songs that nobody has heard yet." On 28 June 2007, the group held a press conference at The O2 Arena revealing their intention to reunite. During the conference, the group confirmed their intention to embark upon a worldwide concert tour, starting in Vancouver on 2 December 2007. "I want to be a Spice Girl again. We are like sisters and we have our arguments, but by the end of the day we get back together", said Emma Bunton, while Melanie Chisholm commented that the tour "will be a proper good farewell to our fans". The group's comeback single, "Headlines (Friendship Never Ends)", was announced as the official Children in Need charity single for 2007, and released on radio on 23 October, whilst released digitally on 5 November and commercially on 19 November 2007.
