Ariana Grande, 31, has put everyone in her circle on notice — they’re not allowed to breath a word about the divorcing pop star’s sudden tumble into love with co-star Ethan Slater, 31, RadarOnline.com has learned.

Insiders spilled that Grande’s close pals were forbidden to speak about the Thank U, Next singer’s romance until ink dried on her divorce papers, as well as Slater’s.

“Ariana has asked all her friends not to talk about it — at least not until both of them are officially divorced,” a source told the National Enquirer.

The insider noted that even Grande’s Wicked co-star and friend Cynthia Erivo recently backed away quickly when asked about the allegedly forbidden topic.

“It’s an uncomfortable situation for Cynthia,” the insider continued. “She was a witness when Ariana and Ethan fell in love. She knows everything but she’s keeping it under wraps.”

As RadarOnline.com exclusively reported, Grande finalized her divorce from ex-husband Dalton Gomez in early October. The pop star agreed to fork over $1.25 million to Gomez, but an iron-clad prenup spared her from paying additional spousal support.

Gomez was allowed to remain in the couple’s Los Angeles home rent-free for 30 days and is set to receive 1/2 of the net profits from the sale of their home.

The former couple also agreed to strict terms regarding interviews on their time together.
