Actress Woori made a guest appearance on Tuesday’s SBS “Strong Heart” and explained the truth behind late last year’s controversial nude photo shoot between her and BEAST’s Yoon Doo Joon.

“To be honest, there’s a secret to those pictures. I was too young and embarrassed to take nude photos at the time, so the photo team used special graphic effects to delete the bikini top I was wearing,” the actress from MBC drama “Heartstrings” said. “It’s definitely not nude so I hope BEAST fans would let loose their anger.”

Woori and BEAST’s Yoon Doo Joon took a semi-nude photoshoot last November for the December edition of Marie Claire magazine in Korea. The photos became a hot topic immediately after its release for Woori’s top naked photos and what looks to be an open flyer on Doo Joon’s pants. It was later clarified that the white part on Doo Joon’s pants were just part of his white shirt slipping out.

This episode of SBS “Strong Heart” will air tonight with other star guests including 2PM’s Taecyeon, f(x)’s Krystal, and Wang Ji Hye. Woori is currently playing the role of Han Hee Ju on MBC drama “Heartstrings,” as the rival of Park Shin Hye.
