Rapper and dad-to-be Wiz Khalifa has been cited for failing to wear his seat belt during a traffic stop in California.

The “Black and Yellow” hitmaker, who is expecting his first child with his model fiancee Amber Rose, was stopped by a cop while driving his new $100,000 Porsche 911 Carrera S on Sunday, hours after attending Rose’s baby shower.

He was ticketed for the offense, and decided to use the opportunity to warn fans about the necessity for traffic safety, telling a TMZ videographer, “Make sure you guys wear your seat belts.”
