Simon Cowell walks down the aisle to get married in church for a Comic Relief sketch.

Those inside the church include JLS star, Aston Merrigold, Amanda Holden, and Alesha Dixon.

Friend and fellow judge, David Walliams, who won't reveal whether Cowell gets married to a woman or man.

The “wedding” was filmed at a church just outside London. Members of JLS dressed up as choir boys and there was even a priest in full regalia.

Former Britain’s Got Talent contestants including Ashleigh and her dog Pudsey and singer Jonathan Antoine also took part.

Cowell used a lookalike to stand in for some of the wedding scenes.

Cowell has also been celebrating the ­success of The X Factor. Nearly 10 years since the first episode, the original judging panel met up for a night on the town.

Sharon Osbourne and Louis Walsh joined his former girlfriends Mezhgan Hussainy and Sinitta at London’s Arts Club on Friday.

Cowell's spoof wedding will be shown on Red Nose Day, Friday March 15, on BBC One.
