After preparing to perform at the closing ceremony of the London Olympics, Robbie Williams has withdrawn from the production because his wife Anya Field is due to give birth around the time.
"Robbie quit a few weeks ago," a source told The Mirror. "He had been lined up to perform solo material and it was hoped he would sing with Take That.
"However, just as rehearsals were kicking off, he said there was an unfortunate clash of dates. It meant organisers had to adjust the entire schedule, because Robbie is an extremely high-profile performer, and had been given such an important role in the finale."
"A lot of organisers are now very unhappy. It's such a huge moment for British music and they thought they had the perfect line-up."
The London 2012 Organising Committee (LOCOG) has been under fire recently for their reluctance to pay the musicians performing at the event, arguing that the exposure and publicity are worth more than payment.
"He [Robbie] was asked to do the closing ceremony but due to the imminent birth of his baby, he couldn't take part," said a spokesperson for the pop singer.
Musicians set to perform at the closing ceremony include Take That, George Michael, The Who, with Beatles legend Paul McCartney ringing in the beginning of the national sports event with the classic 'Hey Jude'.
