There has been a rumor going on about Mo Bamba coming out as gay but there is no authenticity in this news as well he does not have a girlfriend currently.
It has been hard to find out where did the rumor about him coming out as gay came from but there is no official statement proving it from his side.
Likewise, he is quite away from the relationship stuff as seen per his Instagram handle although some netizens are saying that he is in a long-term relationship.
From this, we can believe either he does not want to open up about his girlfriend or is actually single at present and looking for a perfect partner.
