In a classic case of the "for science!" excuse, After School's Lizzy recently revealed that one of her methods of learning facial expressions was by watching adult films.

On a recent broadcast of the radio show 'Boom's Young Street', radio DJ Boom asked, "Your title track "Flashback" is a sexy concept. Wasn't that hard for our Lizzy, who has always been cute?"

"It was very stressful to try to be sexy when I'm not," Lizzy confessed. "So I asked UEE unnie what I should do to be more sexy, and she told me to think about perverted thoughts. So I watched many adult films."

Boom then followed up by asking if it actually worked, to which Lizzy replied, "But I found I just couldn't do those kinds of expressions onstage, and you're not supposed to. So I turned off the lights off at night and practiced by myself."

Her story garnered different reactions from listeners, with one pointing out that "she has been trolled by UEE", while another said - more straightforwardly - "Lizzy is so cute".
