Looks like Jason was having a bad day because a few haters were able to get under his skin.
The two guys seemed to wanted a reaction from Derulo and he gave them just that.
As an artist, I think you should have way more self control especially if you’re not being touched.
This incident was very childish on the 2 guys end but even more immature on Jason end as he’s an artist with a brand fighting fans. Never hit first, he could get sued.
