BRAVEST & BAREST

In hot water for racy model pix

Things are getting a little too hot at one Big Apple firehouse.

A series of Instagram pics shows two smokin’ bikiniclad models getting cheeky with the Bravest at Engine Co. 8/Ladder 2 on East 51st Street in Midtown last week.

“I was on fire,” model Vera Smirnova (left and below) wrote when posting her sexy photos — which include her donning a fire helmet and getting a ride on the shoulders of a firefighter on Friday.

As if that weren’t enough, the same firefighters were also snapped with social-media model Anastasia Fields, who caused a stir last year when she flashed her rear while posing with NYPD cops in December.

The Siberian beauty has since butt-flashed her assets throughout the city — and was obviously at it again Friday.

She posed with a grin while standing on a firetruck in spiked heels, a black jacket and a thong that made it look as if was wearing no underwear — with a couple fireman around her smiling.

In another snap, one of the Bravest holds her in his arms.

She had taken the photos down from her Instagram account by Sunday afternoon, but screenshots were obtained by The Post.

FDNY fire officials were not amused by the firehouse hotties and their Bravest buddies, who appeared more than willing to pose with them.

The images appear to violate the department’s social-media policy, which dictates that “members of the department are prohibited from taking photographs, videotaping or recording audio while working unless authorized.”

“Department is aware of the photos and is investigating,” FDNY officials said in a statement Sunday when presented by The Post with the photos. “Members involved will be suspended.” Last month, Fields told The Post, “The buttflashing thing is just a strategy to attract a lot of followers,” after she posed with the NYPD officers. She currently has 1.4 million Instagram followers.
