The fourth season introduced the concept of the female guest host after Lucy Kennedy's decision to leave the show. Each guest host presented two shows and were obliged to be female. These included Michelle Heaton, Pamela Flood, Amanda Bonkher, Mary McEvoy, Donna McCaul, Rosanna Davison and Bláthnaid Ní Chofaigh. Every second show featured a new slot, "Rhyme Bandits", in which a well-known singer switched genre and performed in the guise of their selected artist in a style reminiscent of "Stars in Their Eyes".
