A$AP Rocky is staying positive despite going to court on a gun charge that could put him behind bars … just take a listen to what he had to say after the first day of his gun trial.

The rapper broke his silence Friday after court wrapped, sending a three-word message to his fans.

Rocky tried to sneak out a side door to avoid a throng of reporters and paparazzi … but TMZ has the first video of him speaking since his trial began.

Seems A$AP seems pretty confident early on … remember, he also rejected a plea deal that would have put him in jail for six months.

Rocky is accused of firing a gun at a former associate outside a Hollywood hotel in 2021 and he’s facing up to 24 years in prison if convicted.

There’s a lot at stake but Rocky is taking it all in stride … at least in front of the cameras.

The first day of trial saw his baby mama Rihanna brought up a few times … and the first witness to take the stand was a police officer with a famous mother.

Rocky’s attorney, Joe Tacopina, also spoke after court and had more to say than his client … talking to us about a lack of Black people on a jury that’s supposed to be made up of Rocky’s peers.
