She’s in high school and dating the star quarterback — of the Jets!

Superstar Gang Green play caller Mark Sanchez “hooked up” in his New Jersey home last month with a striking 17-year-old Connecticut high-school girl — whose preppy dad is a super-wealthy financier, a bombshell new report claims.

Sexy rich girl Eliza Kruger not only bragged on Facebook about “MARK F–ING SANCHEZ” texting her after they flirted at a hip Manhattan nightclub on New Year’s Eve — she also took photos of a mussed-up bed in his boudoir as “proof” of their huddle just days later.

“We went back to his place in Jersey after dinner. He lives on a golf course. There was a big storm,” Eliza told Deadspin.com, according to that website, which identified her only as E.K.

Asked if she “hooked up” with the 24-year-old Sanchez that night — after they dined together at Midtown hotspot Nobu the first week of January — the Greenwich high-school senior said, “Yeah,” albeit somewhat reluctantly, according to Deadspin.

When a Deadspin editor told her he would research the legality, Eliza reportedly replied that the age of sexual consent in New Jersey is “16. I checked.”

“He’s a really nice guy, you know,” Eliza told the site. “He’s one of the kindest people, and he’s a genuine person.”

Eliza’s dad is Konrad “Chip” Kruger, a partner in the Stamford, Conn., financial firm Five Mile Capital Partners, who court records show received a $48 million bonus, severance and a deferred-compensation package when he left the firm Greenwich Capital in 2000.

He also was in a partnership that in 2005 bought 78 percent of the commercial real-estate subsidiary of General Motors Corp. — at a cost of $500 million.

“The return on this investment is potentially staggering,” wrote a Connecticut divorce-court judge in 2006, dissolving the marriage of Konrad and Eliza’s mother, Marie Kruger.

While married, the couple had homes in Greenwich and Massachusetts as well as a “manor house” in London. They also summered on Cape Cod, divorce re cords show.

Eliza told Deadspin that Sanchez continued contacting her after they went to his home.

“He would send me a text at 2 a.m. on a Wednesday asking if I was out that night,” she told Deadspin.

“But I’d be, like, I have school tomorrow.”

In fact, Eliza told the site, Sanchez last texted her at 2 a.m. on Jan. 24 wanting to know if she was going out, hours after he returned from Pittsburgh, where the Jets lost in the AFC Championship.

Deadspin posted photos from Eliza that showed a room with a mussed-up bed, football helmets — including a Jets one and one from Sanchez’s alma mater of Southern Cal — and a montage of photos on a picture titled, “I love you Tio [Uncle] Mark.”

Deadspin reported that Eliza claimed she met Sanchez on New Year’s Eve at the Manhattan nightclub Lavo, where he approached her to chat, flirt and get her BlackBerry number.

“You know I’m 17, right,” she told Sanchez, according to the site.

Sanchez allegedly replied, “Well, we can still talk. But I can’t see you until you’re 18,” Deadspin reported.

Eliza then shot back, “Actually, 17 is legal in New York,” the site reported.

She also reportedly told the website that Sanchez gave her and a friend tickets to the Jets-Bills regular-season finale on Jan. 2, several days before she met him at Nobu.

A Jets spokesman said the team would not comment on Sanchez’s personal life. Sanchez couldn’t be reached for comment.

At her Greenwich house, Eliza’s mom said, “I don’t think she wants to talk. We’re really trying to shut this down.”
