Robbie Williams to perform at dad's wedding

London, Feb 1 (ANI): Robbie Williams has a big gig lined up - his dad's wedding.

Pete Conway performed at his Rob and Ayda's wedding in LA in 2010, so in a way Williams is trying to repay the favour when his dad weds Melanie Mills, the Sun reported.

According to a source, Williams is thrilled, as he is best man and will sing and there are talks that he will do the first dance during the ceremony. (ANI)
