A former EastEnders star, who decided to step away from the limelight and pursue a fitness-focused career, looks unrecognisable since her last appearance on the soap 13 years ago. Child star Molly Conlin first appeared on the BBC show in 2008 as Dot Cotton's granddaughter, Kirsty "Dotty" Cotton, but the now 22-year-old has since swapped acting for picking up dumbbells in the gym.
