Nick Cannon is not currently dating anyone or at least not to the public. However, he has had a share of public relationships with notable celebrities. Probably his most notable relationship was with singer Mariah Carey. This is the only woman he has married and the mother of his first two children. Their relationship escalated from dating to marriage quickly.
Though they are now divorced, they maintain a healthy co-parenting relationship for their children. One of Cannon's first public relationships was with singer and actress Christina Millian. They shared the screen together in the film Love Don't Cost A Thing. Even though he is not currently in a public relationship, Nick Cannon has never had an issue with landing a girlfriend in Hollywood.
It does not look like Nick Cannon is dating anybody currently, and that means he is single. I think Nick Cannon has decided to take things slow and easy after his breakup with Mariah Carey in 2015. However, Nick Cannon has dated so many women after he got separated from his wife. In fact, he had a son with Brittany Bell during their relationship that lasted for about two years immediately after he ended his first marriage.
Nick Cannon was once in a relationship with Jessica white after his first marriage to Mariah Carey, crashed in 2015. Jessica White is an American actress and a fashion model. It seems Nick Cannon now has a lot on his table that he has decided not to go into any relationship for now. And if otherwise, he might also want to keep things going underground while he focuses more on his career and other aspects of his life.
