Ash Benzo – that's the social media handle of 'Pretty Little Liars' star Ashley Benson—covers the March 2014 issue of Cosmo in a cozy sweater, showing off some thigh. The sexified actress spoke about nudity (none for her), drugs (none of those, either) and her on-off ex Ryan Good, aka Justin Bieber's former swagger coach.

Here's what we learned about Selena Gomez's 'Spring Breakers' co-star. For more, grab the issue when it lands on Feb. 4.

She has a no-tolerance policy on nudity: "I never want to do nudity that's gratuitous. Girls look so much better in lingerie or a t-shirt and leave the rest up to the imagination. I make it clear that I have a line. Everyone tries to push you, and it's easy to get talked into doing those things. I'll just walk off-set. But not everyone realizes they can do that."

She likes being a brunette: Benson went darker for a role and loves it, saying, "Brown hair makes me feel more myself. As a blonde, I get categorized as the bitchy popular girl for roles, and I just want to be the normal girl."

She steers clear of alcohol and drugs, but for a good reason: "There are drugs and alcohol in my family on both sides, so I’ve seen lives ruined, going to jail and all that. Once you start with any drug, it can be an addiction – that’s why I never want to start and am not even tempted, because that chain is relentless. And if it runs in your family, you see how unglamorous it is. I would never want to be out of control with my body.”

Ryan Good is still in her life: "Ryan is one of the strongest people I’ve met, so grounded and such a positive influence on people. We took a break because it was so hard. I work 20-hour days, so I’m always gone. So a lot of your relationship is on the phone and iChatting and trying to catch up.”
