Kaori Mai Hart Kaori Mai Hart was born Sept. 29, 2020. She is Kevin Hart's youngest child and his second-born with current wife Eniko Hart. Kevin claims that Kaori will be his last child, and he and Eniko strategically planned the timing of her birth so she'd be close in age to Kenzo. When she was born, Eniko shared the announcement on Instagram, calling her a little bit of heaven! Kevin wanted to make sure he could take time off work to be there for Eniko and Kaori, and it's easy to see by the snaps he's shared of his youngest daughter that he's already so in love with her.
