No. Nick Cannon and Mariah Carey are not back together. Carey is currently dating her background dancer Bryan Tanka. Cannon is not currently publicly dating anyone, but since his marriage with Carey, he has had another child and been linked to many other women. Though they are no longer married, they do have two kids together and have a great co-parenting relationship.
Often on social media, you can see them posting pictures together as a family. Fans are happy to see this because their divorce started out rocky, but throughout the years, they have been able to parent as one.
No, there hasn't been any formal declaration from both Nick Cannon and Mariah that suggests they are back as a couple again. Nick and Mariah got married in 2007, and their marriage was blessed with two kids(twins), Monroe and Moroccan. However, both parents separated in 2014, and their marriage officially ended in 2015. Since then, there hasn't been a real move from both parties about whether they still want to be back as a couple again.
Although, Nick once quoted saying if he were to marry anybody again, it would definitely be Mariah. However, Mariah's response to what Nick said wasn't a sweet one. The reason for their separation was not made open to the public, but both Nick and Mariah have always said they ended their marriage because it wasn't growing as it should and that it was the best option which they needed to take, especially for the sake of their children.
The correct answer to this question is No. They have been divorced since 2014. Even though their divorce started off sour, since that time, they have learned to have a healthy co-parenting relationship. They are also very friendly with each other on social media and on Cannon's show "Wild-N-Out." Both have moved on since their marriage.
Nick Cannon has since had another baby with a model. Mariah Carey has gone on to date a billionaire and is now dating her backup dancer Bryan Tanka. Some fans speculate whether they should get back together, but for now, it seems their co-parenting situation is best.
