It's no secret to any fan that BTS members have always been fans of Girls' Generation for a very long time even the first album purchase of some of the members was a Girls' Generation album. So many fans were happy and surprised when they noticed at the last concert of BTS stadium tour that Girls' Generation member Yuri came to show her support for the group.

Yuri is not the first SNSD(Girls' Generation) member showing her support for BTS. Previously YoonA has attended BTS concerts and has shown publicly how close of a friend she is to BTS member Taehyung who is also very close with SNSD member Tiffany. The rest of the SNSD members have also shown their mutual support in the past and in BTS's early days.

After the concert pictures were posted showing Yuri and her friend wearing BTS merch and lightsticks, happily enjoying their time together after the concert. 

This made fans remember how much both of the groups have shown support for each other over the years and how close some of the members are, along with some of their funny interactions. Here are a few great mentions in fan's tweets!
