Last week, this Web site mentioned that Elton was invited to attend the nuptials of David Walliams and Lara Stone.
He and his partner showed up at yesterday's event, as did names like Geri Halliwell, Tom Ford, Noel Gallagher and Russell Brand.
Davids comedy partner Matt Lucas provided a laugh when he came to the reception dressed as his Little Britain alter-ego, fat-fighter Marjorie Dawes.
Guest Ronnie Corbett said: The funniest moment was when Matt came in. Hed taken all the trouble to bring a wig and costume and brought in the cake dressed up as his Little Britain character. It brought a huge cheer.
The whole atmosphere was of loveliness and glamour from a day gone by. Ive never seen so many white roses, there were hundreds and Ive never been to a more beautiful service in my whole life, it was perfect from beginning to end.
