Star of The Toy Show Adam King is set to appear alongside President Michael D Higgins and a host of other figures for a special Late Late Show musical tribute to Sharon Shannon.
The acclaimed traditional Irish musician will be celebrated on tonight's programme and will arrive in studio for a special night in her honour.
Along with receiving a tribute from the president, U2 bassist Adam Clayton will also be making an appearance.
Sharon will then be joined by several well-known Irish musicians including Donal Lunny, Denise Chaila, Steve Wickham, and Mundy to perform some of her most famous songs.
Sharon's brother Gary and niece Caolinn O'Donovan will also be joining her for the trad session, providing them with a nice family moment this Christmas.
Also appearing on the line-up is Adam King, who captured hearts around the country after appearing in last week's Late Late Toy Show.
Six-year-old Adam from Cork told host Ryan Tubridy that he dreams of working for NASA at ground control.
He had ambitions of being an astronaut before, but said he'd be unable to due to his 'brittle bones'.
After the show, NASA tweeted their support for Adam.
But tonight's programme will be extra special as Adam (6) will be chatting not just with Tubridy, but also with astronaut Chris Hadfield.
Although retired now, Hadfield had an incredibly successful career. He was the first Canadian to walk in space, and flew two space shuttle missions, as well as serving as commander of the International Space Station.
Later Tubridy will be joined by Take That frontman Gary Barlow.
He'll be talking about his productivity during lockdown and performing his latest single.
GAA president John Horan and sports broadcaster Damien Lawlor will arrive to discuss the All-Ireland football semi finals and hurling finals between Waterford and Limerick on December 13.
