Contestants Amelia and Chris are joined by four celebrities hoping to help solve a range of rhyming rounds. In the first team are singer and farmer JB Gill and comedian and impressionist Debra Stephenson, and making up the second team are actress Roxanne Pallett and impressionist and actor Luke Kempner. Chris and Amelia first go head to head in quick-fire animated rhyming round before moving on to play Mime the Rhyme. As Debra and Luke describe a celebrity, JB and Roxanne mime a rhyming action to the celebrity name. It is then on to Rhymewatch, where the teams attempt to identify all the rhyming pairs within a short film starring magician Ben Hart. Finally, it is time for News at Len, where the teams must guess the rhyming headline in four fictional news stories. The contestant with the most points after these rounds goes on to play Rhyme Against Time, where they must solve six three-part rhymes in order to win a holiday.
