Via allkpop:

Recently, Sony Music Japan experienced a slip-up by prematurely posting the cover art for 2PM's Japanese single, "Take Off"!

Though the album art has since been removed from the site, some quick-thinking Hottests saved the pictures. They will be retailing three separate versions of "Take Off", all of which will feature a grand total of four tracks:

01. Take off
02. Heartbeat (Japanese ver.)
03. Take off (without main vocal)
04. Heartbeat (Japanese ver. without main vocal)

Check out the covers for all three versions below!
