Yep, James has finally made an honest woman of Julia after they pair said 'I do' in an intimate ceremony in front of around 60 close family and friends.
However, the reception was another story.
As you would expect from James, it was a star studded affair and around 220 guests included fellow funnymen David Walliams, Michael McIntyre and Jimmy Carr.
With that lot in tow, we can only imagine the pressure on the best man's speech!
However, the best man didn't let anyone down and actually managed to rope in an array of stars including One Direction to star in a special video for James.
Way back when, Mr Cordon was in a pop band (yes, really) and best man Ben Winston recreated one of their music videos with help from Sir Paul McCartney, Robbie Williams, Gary Barlow, One Direction and Snow Patrol.

Honestly for a minute we forgot we were talking about a wedding, and thought we were reading out the list for the Closing Ceremony.
Also invited were James' Gavin and Stacey mate, co-writer Ruth Jones and randomly Natalie Imbruglia and Matt Smith aka Dr Who — who knew those two were mates with James?!
The venue was the super plush Babinton House in Somerset and guests were invited to champagne reception accompanied by an old school band.
What fab news to start off a Sunday, who doesn't love a good ol' wedding, we just wish we had been there to catch the bouquet.
