Park Seo Joon has opened up about his bond with SISTAR's Hyorin. The 27-year-old South Korean actor revealed that the two are good friends.

During an episode of Yoo Hee Yeol's Sketchbook, the host asked Seo Joon about his favorite girl group. He replied: "TWICE. I'm kidding, it's SISTAR. I first saw them during their 'Push Push' days when I was in the army barracks. But at that time, I would have never guessed that we'd become close."

"Whenever an album is released, I listen to everything, even the follow up tracks. I like the follow up tracks more than the title track. I'm thankful to have a friend like her," he added.

Seo Joon continued: "She's my diva. Hyorin is really the only friend I have that's a girl. We're close, so even my parents know her. They know about her appearances more than I do."

Seo Joon and Hyorin began their friendship on the set of Dream High 2. The two played a couple in the KBS television drama series.

In 2013, Seo Joon gushed about the 25-year-old singer. He said: "Hyorin and I are close friends. She has an energetic personality and cool attitude. Even though she is younger than me, Hyorin has become a close friend and we are a good match together" while giving the thumbs up. He also stated, "Because Hyorin is a singer, she talks a lot about the world of singers. I don't know too much about the music industry, but just listening to her talk about it is really fun and interesting."
