Looks like the ladies of 2NE1 will be showing up to Big Bang's 2010 Big Show Concert! Not only will they be gracing fans with their presence, but they will also be performing their hit songs on all 3 days. Perhaps even a joint stage for "Lollipop"? Let's not be too greedy, now. Seeing how great the feedback was when 2NE1 and Big Bang collaborated for other joint stages in the past, this will definitely be highly anticipated by many. The big show is set for January 29, 30 and 31 at Seoul's Olympic Stadium. Who's looking forward to this? Stay tuned at allkpop for more about these two groups uniting on stage!
