The 'X Factor' boss was meant to be his pal Nigel Hall's best man at his nuptials over the weekend, but TV presenter Bradley Walsh was forced to take over the big responsibility a few days before because he said he was too busy to attend.

A source told The Sun newspaper: "Bradley referenced Simon in his speech and said that he only RSVPed that he wouldn't be coming three days before.

"Nigel was upset that Simon couldn't make it. They've been friends for a long time so he really wanted him there."

The 58-year-old music mogul reportedly told Nigel - the Global Head of TV for Syco - that he was tied up in Los Angeles with the new series of 'America's Got Talent: The Champions' but his partner Lauren Silverman would still attend.

An insider explained: "Simon told him that his schedule for filming changed at the very last minute and there was nothing he could do, so Lauren flew in alone."

The wedding was held at London's Claridge's Hotel and saw the likes of Simon's 'Britain's Got Talent' co-judge Amanda Holden and Cheryl Tweedy attend.

Simon was no doubt looking forward to the wedding as he's been working like a "man possessed" recently due to his busy TV schedule in the UK and US.

A source said: "Initially some pals said he'd told them he was too ill to attend but later it transpired it was a schedule clash.

"He's working like a man possessed at the moment. He's just done 'X Factor' judges houses and also America's Got Talent. He could do with a break."
