Jessica Brown FindlayShe’s best known as Downton Abbey’s Lady Sybil, but Jessica Brown Findlay is back on our screens as free spirited Alais in the Channel 4 adaptation of Kate Mosse’s novel Labyrinth.

Jessica, 23, confesses that her nude scene in the film didn’t entail much preparation. ‘I was drinking pints and eating burgers,’ she laughs.

‘I think if you’re going to do a nude scene, be honest and natural. Otherwise I’d be starving myself for ever, which I just couldn’t do!’

But the actress does regret a previous topless role.’To be honest, Albatross was naivety and not knowing that I could say “No”,’ she says.

‘I had no idea what was going to happen and thought I was going to be shot from behind. It’s not something I would do again.’
