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 U-ie 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 U-ie", while another said – more straightforwardly – "Lizzy is so cute".

After School member Nana flaunted her perfectly fit figure.

Recently on an online community forum, a photo was posted along with the title, 'Was After School Nana always this glamorous?'

In the revealed photo, there are captures from the practice video of their new song, "Flashback."

Even in a simple white shirt and black leggings, Nana flaunts her lean and long body line.

Despite the fact that she is just wearing a pair of sneakers, Nana still shows off her perfect body proportions. Her glamorous body and slim 'S' line is receiving much attention from internet users.

Internet users commented, "She's such a model", "Her body is flawless" and "After School has the best bodies among all the idols."

Lee Jang Woo admitted that he had developed innocent feelings for another woman while he andEunjung were apart.

On the July 14th episode of MBC's 'We Got Married', Eunjung was apologetic about not being able to prepare anything special for Jang Woo's birthday this past June.

It seemed as though Jang Woo was trying to console Eunjung saying, "It's okay, my co-host U-ie remembered my birthday."

After School's U-ie and Lee Jang Woo currently co-host KBS 2TV's 'Music Bank' together.

But Jang Woo further upset Eunjung as he added, "There is such a thing as an affair. Receiving a gift like that while we were apart made me feel like it's possible for your heart to wander."
