Former Downtown Abbey star Jessica Brown Findlay recently revealed on Tuesday that she regretted a topless scene in the early part of her acting career.

The British actress who was only 22 years old at the time said she was "naive" when she agreed to strip down in the 2011 movie Albatross, MSN reported.

"To be honest, Albatross was naivete and not knowing that I could say no ... 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," Findlay said.

The actress played a teenager who had an affair with an older man in the film, and one scene revealed her flashing her chest to prove her age. Findlay now wishes she had turned down the request to show her breasts.

Following Albatross, Findlay was later cast in hit-series Downton Abbey, to which she will forever be known as "Lady Sybil Crawley".

"I was in a coffee shop and someone said to me, 'You sound just like an American Lady Sybil!'. I nearly died - how embarrassing to admit that you're walking around pretending to be an American! I thought: 'Oh God, no. You're a proper actor now," she said.

The actress also stripped her clothes in the upcoming U.K. TV drama Labyrinth, an adaptation of Kate Mosse's best-selling novel, but admitted she will never strip down on camera again.

"If you're going to do a nude scene, be honest and natural. Otherwise I'd be starving myself forever, which I just couldn't do! 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."

Findlay said she had no regrets about taking risks which is one of the reasons she decided to leave Downton Abbey in the middle of season three, when the show reach a peak of international popularity and fame. "I didn't want to fall into my comfort zone too much," she explained.

"Being afraid and going into the unknown excites me, and what scared me more was to keep going and then one day discover it was all I could do and wish I had pushed myself more," she told Radio Times, adding that starring in Downtown Abbey was restictive.

"I'd prefer to fail and fall flat on my face," Findlay added.
