Dan Reynolds is the frontman for the rock band Imagine Dragons.
Imagine Dragons have had the #1 song in the US the past 5 weeks (Radioactive). So it only makes sense that he'd be wearing a STL Cardinals hat. As you can see, it works with just about any outfit.
We may or may not be doing a FundAnything for our tipster BF who is still using a .25 megapixel camera. We'll keep you posted.
If you find celebs in Cardinals hats (or any other gear) please pass them along and we'll post.
