Jay-Zis completely at ease after picking himself to perform the Super Bowl halftime show … and he’s not letting any outside noise put him under pressure.

We got Hov in New York City on Tuesday, and our photog asked him if he felt any pressure to deliver a top-notch performance at Super Bowl 61 when the big game rolls around in February.

Jay smiled, laughed, and told us there’s no pressure involved … even though millions of folks across the world will be tuning in.

We also asked Jigga how he’s going to prepare for the halftime show at SoFi Stadium in Inglewood, CA … and it sounds like this is going to be just another show for the GOAT.

As you know … Jay-Z confirmed the worst-kept secret in Hollywood on Monday night, announcing himself as the halftime performer. He picks the acts, and he picked himself.
