The Gossip Girl star insists she will never strip for an acting role because she finds on screen nakedness unnecessary and "distracting" to the plot.

In an interview with Style magazine, she said: "When I see nudity in movies, I am always distracted by it. I know that if I am watching a scene and someone has their boobs out, then that's all I'm looking at - I can't help it. I just don't think that will ever be right for me."

Although she is reluctant to show it off, the 24-year-old actress has an enviable body.

However, Lively - who is the face of Gucci's new fragrance Gucci Premiere - insists she does virtually no exercise to maintain her slim figure.

She admitted: "I am terrible; I don't do any exercise - I'm going to have to learn the hard way. I love food too much, and my family is from the South, so the food I like is not necessarily the best for you.

"There are days when I will be like, 'Oh my goodness, I am not happy with the way I look because I cannot fit into any of my clothes'. So I eat quinoa that week, and then I feel good."

Lively recently purchased a house in New York with her boyfriend and Green Lantern co-star Ryan Reynolds.
