The group 2NE1 reunited to celebrate their 15th anniversary with 3 concerts in their home country of Korea. The 3 concerts of the group, known as one of the "Kpop legends", received a lot of attention from fans and artists in the industry. Many famous people attended this historic concert such as: GD, Daesung (BigBang), the group NewJeans, Jennie Blackpink...
The second and third nights of 2NE1's performances also featured Baby Monster as guest performers. The meeting between the first generation girl group and the third generation girl group from YG Entertainment was cheered by the audience.

During the concert, many interesting moments of interaction between idols were recorded, including Jennie Blackpink's moments that quickly spread on social networks. The moment Jennie took out her phone to film when her junior Baby Monster introduced the group made many people excited. The female Blackpink member also proudly said to the person next to her: "That's my junior."


Besides, videos of Jennie comfortably dancing when her senior performed hit songs like "Gotta be you"... were also recorded and widely shared.
Jennie's move is like an implicit action to erase the conflict rumors with her senior CL - the previous leader of 2NE1. At the same time, she was also praised for the way she cheered on her juniors in the same company.
In addition, 2NE1's concert also helped fans witness the "reunion" of GD and Yang Hyun-suk - former president of YG Entertainment. Previously, GD and Yang Hyun-suk were also rumored to have broken up when information about the dispute over G-Dragon's name broke out.
However, many videos recording the moment GD comfortably chatted with Yang Hyun-suk show that the relationship between the two is still quite good.
