Robbie Williams has confirmed long-running speculation that he is working with Olly Murs on a future collaboration project. The 'Candy' singer admitted exclusively to Capital FM at the Summertime Ball 2013 that the pair have already been working on a secret project, likely to be a team-up track. Robbie said the two got together to work on it back in May, after Olly admitted earlier this year that he would love to record with the Take That singer. "We've done a bit of business together in the last few weeks that should be coming out towards the end of the year," Robbie teasingly revealed to Capital. "In one way or another." Olly Murs joins Robbie Williams on his new 'Take The Crowd' UK stadium tour later this month, and has long admitted to being a big fan of the star. Both Robbie Williams and Olly Murs performed live at the Capital FM Summertime Ball 2013, with Robbie closing out the Wembley Stadium show with a hit-ladden set.Capital FM
