Fans know that SHINee's Key dressed up as Ronald McDonald for Halloween, wearing an amazing costume and face paint. Fans weren't the only ones who appreciated his getup! McDonalds Korea also appreciated it very much.

Key posted some photos on his Instagram, showing how someone from McDonalds sent him a handwritten note as well as a ton of McDonalds coupons! The rep wrote that they were very thankful to Key for showing their brand in a good light.

The SHINee member had previously dressed up as Ronald McDonald at the 'SMTOWN Wonderland 2015' on October 29. He also got into a pretty 'big fight' with Colonel Sanders, aka Onew, as you can see in the video below.
