Zendaya turned up the heat in Harlem for her final Tommy X Zendaya show.

The quadruple-threat actress, singer, dancer and model put all her hyphenates to use in a spectacular presentation that combined a little lip-syncing, a lot of horn and string playing, plenty of dancing, a drive-your-hips-crazy soundtrack and a spectacular array of models of all races, sizes and ages.

She unveiled her “See Now, Buy Now” fall collection at — but not in — the fabled Apollo Theater, one of the neighborhood’s most iconic landmarks. On a loading dock behind the auditorium, her team built an open-air row of historic Harlem townhouses. Better still, she filled it with stoop-set dancers getting down to the sounds of musicians perched in vintage convertibles. It was a blast.

And then there were the foxy clothes. Zendaya flashed back to the ’70s with sharp suits, flared skirts that hit below the knee, slinky bodysuits, silver lamé disco dresses and lots of wide-brimmed fedoras.

Much of the crowd — which included Jameela Jamil, Meghan Trainor, Bella Hadid, Gigi Hadid and her rumored boyfriend, Tyler Cameron — grooved to the music as they exited to the street.

“It was the most fun I’ve had at a show for as long as I can remember,” English model and actress Suki Waterhouse told The Post.

Her friend, Georgia Jagger, said it felt like the ’70s. “It was amazing,” said the model and designer. “It’s all the kind of stuff that I want to wear, like velvet suits. I love it when the music is really good and everybody has really good energy.”

Zendaya’s “Euphoria” co-star Hunter Schafer raved about the immersive event. “It was absolutely beautiful and I’m so proud of Z. I don’t know if you could even call it a runway show — it was like an experience, a performance. It was magic.”
