Irish music manager Louis sported a huge grin as he was photographed outside Coppinger Row in Dublin on Tuesday (11 August).
Proving that he is indeed a very busy man, Louis was seen holding two mobile phones in his hand.
As the longest-standing judge on the ITV talent show, the 63-year-old couldn't escape the attention of fans who wanted to grab a selfie with him.
In an interview this week, Louis said he didn't enjoy being on last year's X Factor.
He said on RTE 2FM: "I liked it and it paid me well but I think I was just there too long and I was cracking up a bit."
After a lengthy 10 years on the show, Louis decided his time was up. His decision to leave came at the same time during which show boss and head judge Simon Cowell unveiled plans to revamp the show.
While Simon and Cheryl Fernandez-Versini remain on the panel, they have been joined by popstar Rita Ora and Radio 1 DJ Nick Grimshaw.
