Channing Tatum has denied claims that he was behind an anonymous Instagram account that posted critical comments about his ex-fiancee Zoe Kravitz.

The actor, 46, shared a statement saying he was not the person behind an account with the username @bidness_nonya, after social media users noticed he was the account’s only follower.

Tatum wrote: “Yo I truly can’t believe yall think this is what I’m doing with my free time.

“F***** hilarious. Also why would I follow a burner account if I didn’t want people to connect me to it? Wtf come on.

“But if I really need to say it, I only have one IG account @channingtatum.”

The @bidness_nonya account appears to have since been deleted.

Tatum and Kravitz began dating in 2021 and got engaged in 2023, before splitting in October 2024.

Kravitz and singer Harry Styles first sparked romance rumours in August of 2025 after a series of public sightings together.

The @bidness_nonya account left a comment on a photo of Styles and Kravitz together, writing:  “When I see these two I think back at how her former fiance called her the most intentional person he knows.

“I wonder how contextual he was being … To me intentional = calculated. He was speaking in terms of film-making but leaning towards her as a person in general too.

“Now she is constantly spotted with Harry compared to the ex who we heard about long before they were seen together. And when they were seen together it was far less frequent.”

Representatives for Kravitz have been contacted for comment.

The account had left positive comments about Tatum in the past, including on a video of him being interviewed, where the user wrote: “He’s so genuine. No false pretences with this guy. And funny as hell, too.”

Kravitz and Styles hit headlines in recent months over speculation they are engaged.

During an interview with British Vogue, Kravitz said she is “aware” of the discussion about her relationship and finds it “overwhelming”.

Kravitz said: “I’m aware it’s happening. I’m aware of when it’s happening, like when there are eight people outside my house, that’s super uncomfortable.

“I’m aware of all the ingredients that create the thing we’re talking about. But that doesn’t mean you’re necessarily OK with it.”

The star said she finds it unhealthy to engage with the speculation, adding: “There are moments, obviously, when you just want to hide because it feels overwhelming.

“And then there are moments when you, whether it’s in a defiant way, are like, ‘I’m going to walk and get my coffee and you’re not going to take that away from me’.”
