Check out the gorgeous moment on Friday's Late Late Show when Katherine Lynch sang Raglan Road, accompanied by archive footage of her late grand-uncle, the poet Patrick Kavanagh.
During their chat Lynch admitted to Tubs that she found Operation Transformation very tough, especially when she realised just how unhealthy she was.
The comedic actress also confessed that she was hugely embarrassed standing in front of the nation in her Lycra crop top.
However, she has no regrets doing the show, as she said if she didn't get herself in shape she would not have done Dancing with the Stars.
