Simon Cowell is getting married - for charity.
The music mogul - who has never wed - will reportedly poke fun at his bachelor status in a sketch for Comic Relief and his famous pals will be the guests at the spoof ceremony.
A source told the Daily Mirror newspaper: "It's an industry joke that Simon will never marry, even though he has dated a string of beautiful women.
"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.
"All Simon's famous friends have Been approached, with Sinitta, Alesha Dixon, Amanda Holden, Louis Walsh and Ant and 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."
Show bosses are keen to keep the identity of Simon's bride under wraps, but the source insists it is not his current lover Carmen Electra.
The sketch will air during Comic Relief on March 15.
