A fearful LA cop pulled a gun on rap kingpin Diddy on Sunset Strip.

The terror began when a Los Angeles County Sheriff’s deputy pulled a member of Sean Diddy Combs‘ entourage at 315 AM Saturday night when cops noticed the rental car didn’t have the proper tags.

The deputy summoned backup after two cars stopped a little too close for comfort. One member of the rapper’s posse was detained when he was uncooperative, prompting six or seven others -including Diddy – to exit their vehicles and advance toward the lone deputy, a source told The New York Daily News.

"A deputy pulled his firearm, fearing for his safety," said authorities. "The situation was deflated as quickly as it began."

The driver was not issued a ticket as the car was a rental.

Diddy’s spokeswoman said the officers were "really respectful."
