She’s “Wheel”-y good at keeping secrets — especially million-dollar ones.

Christina Derevjanik, a 34-year-old marketing manager from Connecticut, made history recently on “Wheel of Fortune” after winning a jaw-dropping $1,035,155 — but she didn’t tell her boyfriend for four months.

“He had no idea,” Derevjanik told The Post after her episode aired September 30th. She explained that she filmed her appearance back in May, just weeks after she began dating her now-boyfriend. Because of strict show rules, she was sworn to secrecy until the episode finally aired.

Admitting that she’s “hit the jackpot with both love and money,” Derevjanik laughed about how surreal the past few months have been. In addition to her cash prize, she also won trips to Montana and Tokyo — and plans to bring her new man along on at least one of the adventures.

While she couldn’t share her life-changing news with anyone, her family noticed something was different. “My parents definitely saw a little pep in my step,” she said with a smile. And for good reason — after taxes, she’s expected to take home around $660,000.

Derevjanik can choose to receive her winnings in installments or as a lump sum. She told The Post she’s leaning toward taking it all at once so she can “quickly pay off [her] student loans and buy [her] first home.”

Surprisingly, Derevjanik’s boss was right there when she won. Her supervisor flew to Los Angeles for the taping, and the contestant even joked on air that she might “put in [her] two weeks’ notice” after winning. But she made it clear that she has no plans to leave her job.

“I’m not quitting the job,” she clarified. “My boss is very happy. I will be continuing to work for her, and I was just so excited that she was able to be part of the experience.”

For Derevjanik, the moment was a dream come true. “I’ve been watching since I was young,” she said. “I had one of the ‘Wheel of Fortune’ handheld games that I would always play as a child in the ’90s.”

Her experience on set was everything she imagined and more. “Everyone who works on the show, and [hosts] Ryan [Seacrest] and Vanna [White], were just such a pleasure,” she said. “They were so wonderful, and they really shared in my excitement, so it was just such a great experience.”

Derevjanik won big after securing the “One Million Dollars” wedge early in the game, earning $35,155 in cash plus her two trips before advancing to the bonus round. Choosing the “Living Things” category, she correctly guessed “PACK OF COYOTES” — and Ryan Seacrest revealed her $1 million envelope.

Only four other contestants have ever won more than $1 million since the prized wedge was introduced in 2008. Now, Derevjanik joins that exclusive club — and she’s still as humble as ever.

A life-changing prize, a new relationship, and a secret worth over a million dollars — talk about a season to remember.
