"Not on my watch!"

Kid Cudi played space superhero during his own Houston concert earlier this week, bouncing a fan before security could run over to help.

As you can see in the video below, during Cudi's "Cudi Zone" performance — as he was dancing around in a space-suit — a random guy started walking across the stage. So Cudi ran over to him and pushed him repeatedly until he fell down. Then security jumped in to help. The crowd cheered and Cudi yelled, "Not on my watch!"

Who knows what that guy wanted or where he thought he was going (did it look staged to you?), but apparently Cudi has a history of this kind of response; in 2009, he allegedly punched someone who threw a wallet on stage.

After the show, Cudi, 29 — who dated and had a song about Amanda Bynesretweeted a bunch of love from concert-going fans, then tweeted himself, "Mission Accomplished! CUD LIFE TOUR 2013 @Logic301 @BigSean @fucktyler BEST TOUR THIS YEAR! SORRY :)......not sorry >:)"

What do you think — should he be sorry, or did that guy ask for it?
