Did you know that today is Leap Second Day? It's like Leap Year, but there will just be one more second added to the clock today – and one minute this evening will have 61 seconds in it instead of 60! How crazy/awesome is that?
In honor of the special day, we decided to quiz you on some celeb styles that you'll need to take an extra second (see what we did there?) to fully process! In all the photos in our gallery, each celeb is missing one element to their outfit, and you'll have to do a double-take to spy what it is!
Click through the gallery to see if you can spot what's missing in each star's outfits. Then, make sure to spend your leap second wisely tonight!
