It’s a football family drama that puts “Friday Night Lights” to shame.

A top NFL executive found out her marriage of five years was a lie — and now she wants more than $30 million for the trauma, plus back pay for gifts she lavished on his son.

Michelle McKenna, a senior vice president and chief information officer of the NFL, is suing the adult kids of her dead “husband,” saying she learned he was still married to his first wife the whole time — and that his son allegedly knew all along but continued to use her as a cash cow after their dad had died.

McKenna married recently fired banker Patrick Doyle in Florida in December 2011, believing he was divorced from his ex, Bernadette Doyle, according to her Manhattan civil suit filed Monday.

Unbeknownst to McKenna, Bernadette had an appeal pending on the divorce — and a judge overturned it in June 2012, court paper state.

That same year, McKenna scored her high-flying gig at the NFL and she used her own funds to buy them a new home in the Rye suburbs.

She says Doyle never worked again until he died unexpectedly in 2017 — instead, she funded his “lavish lifestyle” and also gave money to his adult son, Bradley, her suit alleges.

After Doyle’s $40,000 funeral — which she notes was attended by “numerous high profile individuals, including the Commissioner of the NFL and multiple league executives” — McKenna says she found comfort in her relationship with Bradley, whom she believed to be her stepson.

She continued to help the son out financially — including $13,000 to lease a car, $27,000 to cover his student loans and “all-expenses-paid vacations” for his family, the suit says — but she finally drew the line earlier this year when he asked her to cover his kids’ private school fees.

She claims Bradley then began harassing her via email and texts and smeared her on social media — making “derogatory and libelous statements about her and a friend she hired to be a caretaker to her home while traveling.”

Then in May, Bernadette filed court papers revealing that she was still legally Doyle’s wife — and seeking any assets she might be eligible for from his estate, according to the suit.

To make matters worse, McKenna says she learned Bradley had been aware that the divorce had been overturned all along, the suit alleges — and claims he “malevolently preyed on her compromised emotional state.”

“Still reeling from the sudden loss of the man she thought to be her husband only one year earlier, [McKenna’s] world was shattered yet again by learning that Patrick had defrauded her,” the suit reads.

“So began an emotional roller coaster of anger, anguish and humiliation imposed in a manner that no individual should have to endure.”

When she countered that Bernadette had forfeited any interests to Doyle’s estate by abandoning him, she says Bradley and his sister Lauren took over the petition for the inheritance.

Now McKenna is suing her would-have-been step-kids, and their dad’s estate, for more than $30 million in damages — plus at least $80,000 for all the money she gave Bradley over the years.

She says any money they might be eligible for from their dad’s estate should be returned to her “many times over” for the “extreme damages she suffered” after learning her marriage was a “farce.”

When contacted by The Post, Bradley said he was unaware of McKenna’s suit but insisted she “definitely didn’t financially support me” and alleged that she’d given him a fake will.

“Our lawsuit was over my dad’s financials and things like that — she gave me a fake will and within maybe a month of his passing she was dating a 20-something-year-old-boy. Basically someone younger than me,” he said.

McKenna’s lawyer didn’t immediately return a request for comment.
