No, Jake Paul is not gay. A lot of people might be insinuating this as a way of reacting to a recent post by Jake's brother, Logan Paul, who stated that he would be starting the New Year as gay. This didn't go well with a lot of people as they all used their various ways to criticize Logan. Logan has also reacted by saying he was only joking about the post. Jake Paul has never been enmeshed in this kind of controversy, although he has always been a controversial YouTuber.
Recently, Jake Paul and his wife, Tana Mongeau, ended their six months old marriage. Both stated that they needed to take the decision because they considered it as their best option. The surprising thing about their separation is that they are still supporting each other; according to them, they are still good friends. The fact that Jake Paul just ended his marriage with Tana Mongeau is a confirmation that he was never gay.
