(Yahoo!) - Eternal bachelor Simon Cowell has finally taken the plunge and made an honest woman out of the love of his life: himself.

A hilarious new viral video, shot for the Comic Relief charity's Red Nose Day campaign, depicts the star-studded nuptials of Britain's most lovable egomaniac. Good thing that Cowell is so fond of himself--as it takes a pretty self-assured guy to strut in an ivory wedding gown and a lacy veil on his head.

Wedding guests include Sharon Osbourne, Robbie Williams, "Britain's Got Talent" winners Paul Potts and Ashleigh & Pudsey, "X Factor U.K." judge Louis Walsh, "BGT" runners-up Jonathan & Charlotte, Simon's pop-star ex Sinitta, "BGT" judges David Walliams, Alesha Dixon, and Amanda Holden, "X Factor U.K." host Dermot O'Leary, and "X Factor U.K." alums JLS, Olly Murs, Rylan Clark, and Stacey Solomon.

Sharon, Robbie, Olly, Louis, Dermot, David, and dozens of other guests all attempt to stop the wedding, as they confess their true love for Simon. But the ceremony goes on as planned, because let's face it: A romance like the one Simon shares with his "bride" is unstoppable.
