Charlotte McKinney is the real star of the Super Bowl

Nearly nude, the buxom blonde struts through a farmers market, leaving men slack-jawed.

“I love going all natural,” she purrs, opening wide to take a bite out of a big, juicy, “all natural” … hamburger.

Meet Charlotte McKinney, the 22-year-old model being heralded as the new Kate Upton. A Super Bowl commercial for fast-food chain Carl’s Jr. is about to make this bombshell a star.

A “too hot for TV” version of the ad has already racked up more than 6 million views on YouTube — a number that’s sure to soar come Sunday night.

“It was huge,” McKinney tells The Post of landing the spot. “This guy was literally carrying me to the set — which I’m sure he didn’t mind. I’ve never been treated so like a princess. I could get used to it.”

She just might have to. Having already worked with controversial photographer Terry Richardson and been handpicked by Guess founder Paul Marciano to model for the brand, McKinney’s poised to be the next big thing.

Born and raised in Orlando, she grew up alongside an older sister with parents who run a used-auto dealership, the Car Bar. As a teenager, McKinney cut her teeth in the modeling industry by driving three hours to Miami for swimsuit shoots she describes as “awful.”

Her father saw an opportunity and had her pose for photos in front of cars he hoped to sell. The Car Bar’s website still has a photo of her cheesing in the front of a VW van.

“He’d pimp me out here and there,” she jokes of her dad.

At 17, McKinney dropped out of high school, where she had struggled with dyslexia, to focus on her budding career.

At 5 feet 7½ with a 34-24-34 figure, entering the waif-loving model industry could have been an uphill battle.

“She is on the shorter side, and her measurements are not … the typical model body,” says Craig Lawrence, who signed her to ONE.1 Management in New York. (In LA, Wilhelmina Models represents her.) “[But] Kate Upton opened the doors [and] redefined the parameters of the business, so girls like Charlotte can be thought of as not just a T&A girl.”

McKinney, who stays in shape with hot yoga, Pilates and weight training, has always felt secure in her skin.

So secure, in fact, she had no problem eating that burger in the Carl’s Jr. commercial — well, eight bites or so. She says she generally does enjoy a good burger, though, and has, in fact, dined at Carl’s Jr. before.

“I’m not a big red-meat eater,” McKinney admits, “but I enjoy a hamburger on a Sunday to cure a hangover.”

Fine print at the end of the 30-second Carl’s Jr. commercial reveals that the burger’s “all-natural attributes” apply only to the grass-fed, free-range beef that’s free of added hormones, steroids or antibiotics.

McKinney, on the other hand, she says she’s the real deal across the board.

“I’m all natural,” she says. “Throughout high school, with bullies and everything, [they said,] ‘Oh, she got fake t—s when she was 15 and blah, blah.’ No. I woke up one morning, and I had them.”

As for what McKinney considers her best physical asset, well, she’s on the same page as the fellas ogling her in the commercial.

“I mean, let’s state the obvious,” she says, laughing.

But despite the twins being her favorite body part, McKinney doesn’t know what her cup size is: “I fluctuate. It depends on what’s going on,” she says. (For what it’s worth, her agent Lawrence says, “She looks like a D-cup to me.”)

Those curves are what remind people of former Carl’s Jr. model Upton. Though McKinney says she’s “extremely flattered” by comparisons to the competition, she sounds tired of the topic.

She’d rather talk about her personal inspirations, like Brigitte Bardot or … Anna Nicole Smith.

“I know it’s weird to say,” she says. “But she was so sexy and funny, and [had a sense of] humor.”

McKinney’s keeping her private life private for now — even though dudes everywhere are going to wonder if she’s taken.

“That’s for everyone to guess,” she demurs. “I’m enjoying myself, let’s say that.”

That extends to her career as well, of course. Next up, she’s shot a sequel to “Joe Dirt” with David Spade. She plays a sexy logger (yes, a logger) and says we’ll get to see her humorous side.

With a knowing chuckle, McKinney teases, “You may even see a little more than that.”

On set today for #joedirt2
