Plainclothes cops recovered a trove of loaded guns and drugs at a rap video shoot in Brooklyn attended by hip-hop heavyweights including Busta Rhymes, French Montana, and Juelz Santana, police sources said.

Concerned area residents called the police around 6:15 p.m. after they saw the impromptu crowd of about 200 performers, extras, and gawkers milling around the parking lot of the Bravo Supermarket at the corner of Fulton and Linwood streets in Cypress Hills, cops said.

When they arrived, the plainclothes officers worked the throngs until they allegedly spotted what appeared to be a gun in the pants pocket of 35-year-old shoot security guard Frank Bartlett, police said.

They identified themselves to the 6-foot-11, 350 pound guard, he copped to carrying the 9mm Daewoo, and surrendered, sources said.

As word of the bust spread through the crowd, others started desperately trying to ditch their own contraband.

Cops arrested Ronald James, 32, and Ebonee Eastmond, 27, after he allegedly tried to pass her his loaded .22 Davis Industries derringer, authorities said.

Edward Elkins, 36, was nabbed with a loaded .40 caliber Para Ordinance pistol wrapped in a black, plastic bag between his legs, and 30-year-old Wendy Miranda allegedly dropped a .32 caliber H&R revolver near a row of parked luxury cars including Rolls-Royces, Ferraris, and BMWs, sources said.

A Ziploc bag of coke, some marijuana, and several tablets of Molly were also recovered along with the four loaded guns, police sources said.

It wasn’t immediately clear who the featured artist in the video was, but the shoot was arranged by French Montana’s Coke Boys Records, sources said.

In addition to the former Khloe Kardashian beau, who was an associate of recently slain up-and-comer Chinx, the shoot was attended by Ja Rule, and Noreaga, sources said.

None of the hip-hop luminaries was arrested or charged with any wrongdoing, sources said.
