Carr managed to make headlines for a mini routine which he delivered in front of Shelvey's guests as the former Liverpool player married ex-S Club Juniors star Daisy Evans.
Perhaps predictably, a video of Carr performing which Shelvey uploaded to Instagram proved to be a huge hit online.

The comedian's performance was apparently unexpected for everyone except the bride and groom, who hopefully enjoyed what he had to say.
One joke from Carr in particular has featured prominently on social media platforms since with him comparing Liz Hurley to his own partner.
Shelvey, who scored three times in 31 appearances for Swansea last season, took the opportunity of the summer break from Premier League action to tie the knot with Evans.
Swansea's upcoming campaign begins on August 8 with a trip to face champions Chelsea at Stamford Bridge.
