Well, turns out Megan and Kathryn aren't so identical anymore...
Of course, their faces are still pretty much the same and there's no denying that the girls are twin sisters, but Megan is now training as a bodybuilder and her transformation has considerably helped in telling the two apart.
Just look at how ripped her muscles are these days!
Megan's transformation has been doing the rounds online in the last few days and we're not surprised, as the actress looks dramatically different. She's been weight training for the last three years and has built herself up some serious biceps, as well as one very gym-honed six pack.
Her Instagram feed is constantly showing off her buffed up bod and her training progress, as Megan is currently preparing to compete in a UK Bodybuilding and Fitness Federation Bikini-Fitness event.
She's pretty dedicated to impressing at the competition and as well as hitting the gym, Megan has been following a strict diet programme too, meaning no donuts for her just yet - they're her fave.
Megan is documenting her journey in her very own documentary titled Megan Prescott: Dumbbells and Donuts that is currently in production.
She looks a far cry from her Skins character Katie Fitch from eight years ago, right? Megan played Katie, the more outgoing twin, on the series that followed the lives of a group of teenagers.
Her sister Kathryn, meanwhile, played the quieter and more introverted twin Emily and has since continued to act. She went onto play the lead role in MTV series Finding Carter for two series and is currently filming new comedy movie Dude alongside Pretty Little Liars star Lucy Hale.
