From April 15-16, British rock band Coldplay performed at Seoul's Jamsil Olympic Stadium. 

The band must have had a chance to explore Korea during their visit because after they wrapped up their concert performances, band member Chris Martin took to Coldplay's official Twitter to post a photo of a monument. He also gave a shoutout to popular Korean indie band

Not only that, but numerous celebrities were spotted attending Coldplay's concert over the course of the two days, including EXO's Suho and Chanyeol, BoA, Leeteuk, Sohee, Kang So Ra, F.T. Island's Hongki with Kim Soo Hyun (a.k.a "alien"), JYJ's Jaejoong, and more. 

Looks like everyone had a good time!
