Jessica Brown Findlay is feeling regret about her topless scene in the 2011 film "Albatross."

"To be honest, "Albatross" was naivety and not knowing that I could say no," Brown

Findlay told magazine the Radio Times on Tuesday.

"I had no idea what was going to happen and thought I was going to be shot from behind," Jessica added.

In the film "Albatross," Brown Findlay lifts up her shirt to prove she's old enough to buy cigarettes.

"It's not something I would do again," Jessica added.

Yet, the former "Downton Abbey" actress has reportedly said 'yes' to nudity once again.

This weekend Jessica Brown Findlay will appear in an adaptation of Kate Mosse's best-selling novel "Labyrinth" for British television. She reportedly has another nude scene.

"If you're going to do a nude scene, be honest and natural," Jessica told Radio Times on Tuesday. "The idea that actresses would work out at the gym for a thousand hours before hand... I was drinking pints and eating burgers. But actually, it's not something I would do again."

With parallel plotlines in 1209 and 2005, "Labyrinth" stars Brown Findlay as a young herbalist from the past responsible for hiding the secrets contained within three sacred books.

Jessica's nude scene in "Labyrinth" is reportedly very brief.

"In 'Labyrinth' it is a very fleeting moment that we shot in one take, but I did find it very odd being naked in front of lots of people," Brown Findlay said.

If it's topless, hopefully Jessica won't regret this one.
