Well, he did get them together. And he does enjoy a good wedding - whether it be bursting in to perform a song for the first dance, or providing a platform for a proposal. In short, he's a regular russety Cupid. And it's quite the leap from just being an usher. 

A source speaking with The Daily Star revealed: "They both agree it would be tons of fun as well as extremely fitting if Ed's the one to join them in holy matrimony. He had already agreed to perform a couple of ballads after they exchange vows, so it seemed logical to him that he should get them hitched too."

Seemingly one of Ed's many friends had this to add to the mix: "He's bursting with pride to have played matchmaker to Johnny and Court and he’s told them he's up for anything that will help make their special day truly memorable."

Obviously to officiate, Ed won't have to become a man of the cloth; it's fast becoming the norm for friends to marry their friends, with Jimmy Kimmel helping Justin Theroux and Cox's friend Jennifer Aniston get wed. But let's not forget who kicked off the trend.
