The guests who will be joining Ryan Tubridy on 'The Late Late Show' tonight have been announced.

Returning to the show after his popular appearance on last year's 'Late Late Toy Show' is young John Joe.

Speaking about his guest, Tubridy said: "To celebrate the clocks going forward this weekend I’m delighted to have the show’s favourite young horologist back on the show."

"John Joe stole the show when he appeared on 'The Toy Show' last November so it’s great to have him back on."

Since his last appearance on the show, John Joe became an Internet sensation, getting over 250,000 views on YouTube, nearly 50,000 Facebook fans and his very own YouTube music remix.

Television presenters Derek Davis and Thelma Mansfield will also be reuniting on tonight's show, to take a nostalgic look back at their time together on 'Live at 3'.

Renowned singer Paul Brady will also be appearing on the show to celebrate the release of his tenth album.
