The music mogul splashed a whopping £30,000 (AED 142,327) on a 'Greatest Showman' themed birthday party for his son Eric's fifth birthday.
Cheryl Tweedy, Alesha Dixon, Katie Piper, Rochelle and Marvin Humes were in attendance with their children at the party in Knightsbridge on Saturday.
A source told The Sun: "The kids got to sing their favourite songs from the film and the whole place was decked out just like the circus. Everyone was joking that Simon was like Hugh Jackman's character because he was the ringmaster."
Simon had previously confessed he thinks fatherhood has transformed his life.
