Ryan Tubridy has managed to bag another big name for tonight's bumper 'Late Late Show'.

Clear your schedules, put the phone off the hook, and grab a cup of tea as the infamous Niall Horan will be joining Ryan virtually on the 'Late Late Show' for a very special appearance. A late addition to the show, but a welcomed one at that, the Mullingar singer will be chatting to Ryan from his home in London. Niall Horan on 'Late Late Show' always manages to be a great television, so we've got high hopes for tonight's guest spot.

Along with Niall, tonight's show has already announced that Taoiseach Leo Varadkar will be addressing the nation on what we can expect over the next few weeks and months, as well as 'Normal People' star Paul Mescal on his new-found fame (and the reaction the series has been getting).

Continuing on from their live versions of songs from well-known Irish musicians, Picture This will be in studio performing a number of tracks for charity.

We recently caught up with Niall to talk about his new album, retiring in Ireland, and how he manages to get a decent pint of Guinness while he's off making a name for himself out abroad. You can check out that interview right here.

Tune into the 'Late Late Show' tonight on RTE One at 9.35pm.
