Steve Rogers:
Katy Perry (You shouted when she came out, and Steve just smiled at you.)
Tony Stark:
One Direction (He might've gotten slightly jealous as he watched you fawn over Harry.)
Bruce Banner:
Justin Bieber (He scowled as he watched Justin bring you up to the stage.)
James Buchanan Barnes:
5 Seconds of Summer (His metal arm tightened around your body as he watched you scream and shout over Luke Hemmings.)
Loki Lauyfeson:
Demi Lavato (He may have teleported the two of you into the concert...)
Thor Odinson:
Twenty One Pilots (He shouted 'How dare you fawn over the Son of Odins Queen!' as he watched you scream at Tyler and Josh.)
Peter Parker:
Fall out boy (He frowned as you screamed and grabbed Patrick's hand.)
Sam Wilson:
The Lumineers (He laughed as you jumped up and down as they sang 'Angela' and 'Ophelia')
Clint Barton:
Aaron Carter (He's not going to lie, but he wrapped his arms around your waist as he watched Aaron wink at you. He was the only one who was allowed to do that.)
