Amid speculation that he’s the secret owner of an Instagram responsible for leaving shady comments on his ex Zoë Kravitz's account, the Step Up star addressed the rumors, denying being the unnamed user.
"Yo i truly can't believe yall think this is what l'm doing with my free time," Tatum wrote in a statement shared to his Instagram Stories Sept. 21. "F--kin hilarious."
And the 46-year-old also pointed out a notable flaw in the online theories, many of which claimed the mysterious Instagram was only followed by Tatum's verified account.
"Also why would I follow a burner account if I didn't want people to connect me to it?" he continued. "Wtf, come on."
In fact, Tatum—who shares daughter Everly, 12, with ex-wife Jenna Dewan—closed out his message by assuring fans there's only one place they should go if they want to hear directly from him.
"If I really need to say it," the Magic Mike actor added, "l only have one IG account, @channingtatum."
Days before Tatum cleared the air, internet sleuths noticed an account named "Nonya Bidness" was commenting below several Instagram posts about Harry Styles and his fiancée Kravitz, who Tatum was engaged to before calling it quits in 2024. Under one post about a PDA moment between the "Watermelon Sugar" singer and High Fidelity actress shared, the account wrote in a since-deleted comment, "Just here for the hate."
Soon after, theories emerged that the trolling came from Tatum due to the Instagram profile appearing to only be followed by his official account.
And while Tatum—who is currently dating model Inka Williams—may be staying tight-lipped on his past relationship, Kravitz has previously shared that she has no regrets about their romance, which began in 2021 and fizzled out shortly after the release of their 2024 film Blink Twice.
“I love this thing that we made together," Kravitz told Elle in 2025, "and I care for him very much.”
She added, “I’m so happy that all happened. I just feel so grateful to go on that journey together.”
