In 2007 the Spice Girls regrouped and announced plans for a reunion tour, from which they were said to have earned £10 million each (about US$20 million). The group's members said that they were still enjoying "doing their own thing". The group decided to tour as a quintet for the last time and release their first compilation album, a collection of their "Greatest Hits". This album was released in early November 2007, and the tour began on 2 December 2007. During the reformation, film maker Bob Smeaton directed an official film of the tour, which he titled "Spice Girls: Giving You Everything". In addition to their sell-out tour, the Spice Girls were contracted to appear in Tesco advertisements, for which they were paid £1 million each. In March 2010, vocal coach and singer Carrie Grant announced on ITV1's "The Alan Titchmarsh Show" that Halliwell would be making a return to music. In April 2010 Halliwell posted a message on her website, saying she was back in the studio and referring to Lady Gaga as one of her influences. In May 2011 reports suggested that Halliwell would be making a return to music. On 31 July 2011, Halliwell confirmed she had been working on her fourth album, stating of it, "The album's pretty much finished."
