Lee Seung Gi was a special MC for the September 9 broadcast of the SBS variety show 'My Ugly Duckling.' During the episode, he opened up about how his family deals with his fame, especially his younger sister.

"As far as siblings go, I have one younger sister. She isn't open about the fact Lee Seung Gi is her older brother," he confessed, adding that his parents are also secretive about it.

"We're all that way. Good-looking Lee Seung Gi is hiding, and ugly me is hiding too," the show's host Seo Jang Hoon joked in response, causing laughter.

Lee Seung Gi then commented that he and his sister actually resemble one another a lot, though "she hates hearing people around her say, 'You look like Lee Seung Gi.'"

Meanwhile, the actor-singer continues to appear on SBS's 'The Butlers.'
