Robbie Williams was holding on to quite the treat for fans at his gig at London's Troxy.

The current Take That line-up - Gary Barlow, Howard Donald, and Mark Owen - joined the singer on stage to present him with the Brits Icon Award; as part of the singer's special one-off gig to celebrate the prestigious honour.

The quartet also performed together some of the band's past hits, 'The Flood' and 'Back for Good'; before Donald joked, "Rob, whether you like it or not, you will always be a member of Take That."

Take That's surprise appearance came mere hours after the Mirror reported that Williams had responded to questions about a possible reunion in the negative; insisting, "It might happen, who knows, but right now I don't think so. Reunion at some point, definitely - but we just couldn't get our diaries to work in the next 12 months."

With the band originally disbanding in 1996, its members reunited without Williams back in 2006; Williams himself rejoined briefly in 2010 for album Progress, before a second (amicable) departure in 2014, itself swiftly followed by Jason Orange also taking his leave of the band.
