The list of K-Pop stars who came to BLACKPINK's concert in Korea is long enough to fill an entire awards show.
The first concert of BLACKPINK's "BORN PINK" World Tour was on October 15 at the KSPO Dome in Seoul. Thousands of people from all over the world came to the event, and many well-known Kpop stars who are friends with BLACKPINK members were also there.
Lisa's mother, along with the female idol's family and friends, flew from Thailand to Korea a few days before the event. On the day of the concert, the mothers of Lisa, Minnie ((G)I-DLE), and Sorn (CLC), as well as Minnie and Sorn, came to support BLACKPINK. This showed how close Thai K-Pop idols are to each other.
Mina and Jihyo from TWICE were also seen sitting in the audience area. The two 97-liners got there early and took their seats because they were excited to see BLACKPINK perform offline.
Hyeri, an idol-turned-actress, also showed that she was there by tagging the BLACKPINK members in her Instagram story.
WINNER's Seunghoon was also there to support his juniors and close "sisters." ITZY's Yuna and Lia, who are known to be BIG fans of BLACKPINK, were also there.
On the first night of their concert in Korea, BLACKPINK sang hit songs like Pink Venom, Tally, Pretty Savage, How You Like That, Crazy Over You, DDU-DU DDU-DU, Play With Fire, Whistle, Kill This Love and more.
The stage clothes of the YG Entertainment girl group were also praised. People liked how the members sang with the live band and did powerful choreography at the same time.
BLACKPINK is putting on a very exciting show on the first night of the BORN PINK concert. The fact that K-pop stars showed up shows that the 4 girls have a lot of charisma, are famous, and have a lot of friends
