Luhan joined the photo / video sharing social networking service�back in April, and he's been faithfully updating his fans on his whereabouts and how he's been doing on his account (unlike a certain other EXO member...). The only other K-pop stars with over 2 million followers on Instagram are G-Dragon and Taeyeon, but both artists joined the SNS long before Luhan did.
