In late 2006, Lytton took part in the fourth series of the popular BBC One reality television programme "Strictly Come Dancing". Aged 17 at the time, she is the youngest contestant to have appeared on the show. Louisa's professional dance partner was Vincent Simone. After several impressive performances she was eliminated in the quarter-finals, finishing in fourth place out of fourteen, losing out to Emma Bunton in the viewer vote for a place in the last three. Despite this, Lytton appeared in the Christmas Special on Christmas Day with fellow contestants Mark Ramprakash, Matt Dawson and Emma Bunton, along with 2005's finalists Zoë Ball and Colin Jackson. This show was won by Jackson. Below is a scoring recap from start to finish.
