"We really enjoyed watching it!" Actor Lee Je Hoon and director Yoon Sung Hyun support Jisoo on Day 1 of BLACKPINK's 'Born Pink' finale concert

Actor Lee Je Hoon and director Yoon Sung Hyun were among the many celebrities in attendance on Day 1 of BLACKPINK's 'Born Pink' finale concerts in Seoul.

On September 16 KST, Lee Je Hoon took to his personal social media to share Instagram stories of him and Yoon Sung Hyun joined by BLACKPINK member Jisoo backstage. The two men proudly hold their BLACKPINK lightsticks as they pose with the idol, who has two red flowers attached to her hands in a fashion reminiscent of her solo music video "Flower." The photos were captioned with, "We really, really enjoyed watching it 🖤🩷 Thank you, Jisoo~*."

While Lee Je Hoon is among a number of Jisoo's actor and actress friends who attended the Day 1 show, industry-savvy fans were quickly excited to see Yoon Sung Hyun coming out to support Jisoo specifically, as the director will be helming the upcoming zombie drama 'Influenza,' which Jisoo had previously been approached to star in.

Meanwhile, today (September 17) is the final day of BLACKPINK's 'Born Pink' world tour, wrapping up with Day 2 at Seoul's Gocheok Sky Dome. The tour went on for roughly 11 months, with the group visiting 34 cities overall.
