India, Sept. 23 -- M agic Mike star Channing Tatum has laughed off a viral internet theory that he was secretly using an Instagram burner account to troll his former fiancee Zoe Kravitz and her fiance, singer Harry Styles.

Screenshots of the account's comments quickly circulated online, including one under a picture of the couple that read, "Just here for the hate." Tatum, 46, finally addressed the online sleuthing on his Instagram Story on Monday, writing, "Yo, I truly can't believe you all think this is what I'm doing with my free time. Fu**in hilarious."

Clarifying that the account was not his, Tatum wrote, "I only have one IG account @channingtatum." The disputed account has since gone offline. HTC...
