Episodes Broadcast: 2007

Porsha Lawrence-Mavour first came to national attention in 2002. Just ten years old, she was a finalist in the inaugural children's edition of the reality competition Stars In Their Eyes; she sang the 1956 single My Boy Lollipop, which had been a hit in 1964 for Millie Small. Lawrence-Mavour then acted on stage, before winning the role of Kelsey Hooper in the Doctor Who spin-off The Sarah Jane Adventures. Kelsey appeared in the debut episode, Invasion Of The Bane, which aired on New Year's Day 2007. However, plans for the character to continue were scuppered when showrunner Russell T Davies concluded that a better gender balance was needed as the show proceeded to its first full season. Consequently, Lawrence-Mavour was replaced by Daniel Anthony as Clyde Langer; Kelsey would prove to be her only television role.
