Seeing Double is the fourth and final studio album from S Club. It was the only album to be released under the name "S Club", after the group was rebranded when Paul Cattermole left the group in June 2002 after his departure announcement in March. It was used as the main musical influence to the film of the same name released in April 2003. Despite good reviews and reception, the album only managed to reach number 17 on the UK Albums Chart.
