So here's Rory, back at Ravenhill to cheer on Ulster in their interprovincial game against Connacht.
And he didn't come solo - bringing the British Open Claret jug along to show the fans.
Rory was approached for an interview by BBC Northern Ireland and the stadium PA picked that moment to blare out 'sweet Caroline' - a reference of course to Rory's ex Caroline Wosniacki, who often accompanied McIlroy to Ulster Rugby games.
Rory clocked the joke, reacted with a wry smile and an 'oh dear', and got on with it.
Good sport.
