The music mogul is getting ready to walk down the isle, but it's just for charity.
Simon is set to star in a sketch for Comic Relief, playing on the countless jokes about his less than successful love life.
“It’s an industry joke that Simon will never marry, even though he has dated a string of beautiful women," a source told the Daily Mirror today. “So for this year’s Red Nose Day, he’s willing to send himself up to raise money on the night.
"All the Britain’s Got Talent team will be involved, with rumours that David Walliams will declare his love for Simon in a bid to stop the marriage."
The insider went on to tease: “All Simon’s famous friends have Been approached, with Sinitta, Alesha Dixon, Amanda Holden, Louis Walsh and Ant ’n’ Dec being asked to join in, along with a host of Simon’s ex-loves.
“Loads of contestants have been invited, like Rylan Clark and the Showbears for added campness.
"They’re going to be filming it over the next few weeks, on a day when, hopefully, everyone can make it. It’s bound to be one of the highlights of the telethon.”
Comic Relief will air on BBC One on March 15.
