Let’s face it — most book parties are dull. And one might not expect a guest list full of news ­anchors to spice things up a whole lot.

But at a bash crawling with media types for former CNBC “On the Money” host Carmen Rita Wong’s debut novel, “Never Too Real,” fellow media insiders went so wild, one former veteran CNN and Fox News anchor wound up doing back flips with a “hot server” — and even traded dresses with a hostess.

At the Thompson Square Studios party for the tome — where guests included WNBC’s David Ushery, OWN host Andrea Syrtash, MSNBC executive producer Eric Salzman, CNN “Money Matters” correspondent Maribel Aber and staffers and talent from The New York Times, Slate, ESPN, BET, NPR, SiriusXM — a dance party broke out to old-school hip-hop.

A spy said that’s when former CNN “American Morning” and Fox News anchor “Kiran Chetry had such a good time, she ended up doing back flips on the dance floor with a really hot server . . . Not kidding.”

Another insider said, “It was a blast! She also traded dresses with a hostess!”

A witness explained that Chetry, 41, was in the ladies’ room with a hostess who complimented her dress, and Chetry generously traded frocks with the woman and emerged in a different dress. An impressed spy said, “She’s 41 and she traded dresses with a hot 20-something and she looked gorgeous.”

Ushery, who had just returned from covering the Orlando, Fla., massacre, “salsaed in his suit” with producer wife Isabel Rivera, and “the whole staff ended up dancing,” shutting down the venue.

Meanwhile, we hear that Wong — whose book is described as a “multicultural edition of ‘Sex and the City’ ” — already has a sequel due in April and has been in talks for a TV adaptation.

Chetry — who’s launching the Nepalese American Magazine, tweeted at us: “it was a front flip! I’m way too old to attempt a back flip. @CarmenSense had the best DJ. And I love to dance.” And, “u did get the dress thing correct! I learned from grandma, Give! ‘Things’ matter little. It looked better on her anyway!”

When reached for comment, Wong said of the wild bash, “My parties bring this out in people . . . The dancing was on point.”
