PITTSBURGH (KDKA) – As an entertainer, Pittsburgh native Wiz Khalifa is used to being the center of attention.

However, his actions prior to throwing out the first pitch at PNC Park on Wednesday have drawn the ire of Major League Baseball.

Khalifa took the mound wearing a “Legalize It” T-shirt. Before Khalifa wound up, he made a puffing gesture.

Well, it didn’t sit well with MLB.

According to the Tribune-Review’s Rob Biertempfel, MLB issued a statement saying, ““Marijuana is [a prohibited] substance in all of our drug programs. It’s unfortunate this situation occurred. The Pirates have informed us that this should not have happened.”

It’s not the first time Khalifa has made a public display of this nature.

In 2012, the rapper wore a “DOPE” hat to City Hall for the proclamation of Wiz Khalifa Day in Pittsburgh.
