Fans of Taeyang who also follow Rihanna's Instagram account 'badgalriri', noticed that she followed Taeyang's Instagram account 'youngbeezy'.
This isn't the first YG Entertainment artist for Rihanna to follow as she followed 2NE1's CL Instagram account earlier in the year.
Fans are pondering the possibility of a potential Taeyang and Rihanna collaboration in the future. Would you like to see that happen?
