WhereasEliza Dushku was thinking what we all were thinking: "Wait, I'm still stuck on #Bieber is #Mayweather's #HypeManJr..? #Alvarez #FightNight"
Spade didn't hold back, Instagramming a pic of their entrance with the caption: "WTF?? One of these things doesnt belong. He needs to be cropped! #teamcoughsyrup"
