The Dubliner joined Miriam Margoyles and Sarah Snook on the couch
It's fair to say that CMAT is absolutely killing it right now - and it seems that the rest of the world is starting to catch on to the Dubliner's talent, too.
The Irish musician, who recently released her second album 'Crazymad, for Me', has been making friends and influencing people in the UK in particular, and one of them is Graham Norton.
Norton invited her onto the show on Friday, where she performed her new single 'Stay for Something' and joined Miriam Margoyles, Sarah Snook, Gretta Lee and Boy George on the sofa for a chat.
It seems that she also had a bit of craic with Margoyles backstage, too...
