Fire stud caught in ‘Wife Swap’ split

The smokin’-hot firefighter who sparked an FDNY scandal with a full-frontal nude video is embroiled in another scorcher — he’s named as the “other man” in the New Jersey divorce of a reality-show contestant who stabbed her husband, The Post has learned.

Five-alarm hunk Michael Biserta, of Brooklyn’s Ladder Co. 131, traded sexually explicit mobile Facebook messages with former “Wife Swap” star Jamie Czerniawski just before her knife-wielding rampage last Memorial Day weekend, court papers allege.

In lusty texts exchanged between May 12 and May 25, Czerniawski and Biserta discuss plans to rendezvous, according to a Monmouth County Divorce Court complaint filed by Jamie’s husband, Charles.

“I want to let you know just how f- – -ing bad I wanna f- – – you right now!!!! Can you get out??” Czerniawski, 30, asks Biserta, 25, in a May 18 text.

Earlier that day, she wrote Biserta: “I miss your lips!”

“Want you,” the handsome hose man replied.

“Mmm, can’t wait!!!!!!!!!”” she texted.

At one point, Biserta and Czerniawski appear to discuss a firehouse hookup.

In a May 19 exchange, Biserta texted, “I want to see you more . . . we gotta make some time.”

She replied that she could “def” visit him at the firehouse.

Biserta wrote back: “If your [sic] in Brooklyn you can stop by. [It] won’t be like last time so I wouldn’t even bother . . . it’s usually not that quiet around the fh [firehouse] but we’ll work something out . . . ”

In late 2007, Biserta ignited the ire of FDNY Commissioner Nicholas Scoppetta when — after the firefighter was chosen as the cover boy for the department’s 2008 fund-raising calendar — it emerged that he — and his God-given fire pole — had appeared in a 2004 video, “Guys Gone Wild.”

Scoppetta halted all future FDNY beefcake calendars. Biserta wasn’t disciplined because the video was made before he joined the FDNY in 2006.

In February, the fire stud got engaged in to Staten Island girlfriend Danielle Cipriano and plans to marry her on Oct. 10, 2010, according to their wedding Web site.

But the engagement apparently didn’t douse his fire for Czerniawski.

At around 3 p.m., May 25, Biserta texted: “This sucks . . . I’m working toooo much lately . . . I want youuuu.”

Ten hours later, Jamie — who traded places with a freak-show performer for a 2006 “Wife Swap” episode — stabbed Charles in the arm during an argument.

Charged with aggravated assault, she claims she acted in self-defense. Her husband contends she wanted him to die.

Reached at his parents’ Staten Island home yesterday, Biserta declined to comment. An FDNY spokesman also declined to comment.
