Samuel Soba is not a popular name and is not recognized that easily by the people so far. People won't know him unless his identity is reveled i.e he is the husband of a very famous American actress and entertainer, R&B and pop singer and songwriter. There is no confirmed information available on any media about his family background and his personal life. He has got a good physique and attractive personality which can be said by the picture uploaded by his star wife. He seems to belong to Black American community.
As we already said, his profile is kept very low. We exactly can't say whether he had some girlfriends at past or may have child from them. The only way he is popular in front of public is because of his wife. He is not much active in the social media as his wife, so that we can track his information down. We can only assume that he must be talented in his field of work and had worked hard to win the heart of such a popular diva.
