On September 15, BIGBANG's Taeyang updated his Twitter with a photo of him along with his buddy G-Dragon to congratulate on him on his successful performance.  Earlier that month, 2NE1's Park Bom had also updated her Twitter with a backstage photo for the preparation of their concert. Comparing both photos, fans noticed many similarities.
