When it comes to Dakota's personal life, the actress is extremely private. She and Chris waited months to confirm their relationship publicly, and there was even a period of time where fans believed the couple had split because they hadn't been seen together in so long.
Because of this, we have no idea if Dakota has any plans to have children, but considering the multiple false pregnancy claims, it's safe to say that right now the actress is childless.
That being said, she and Chris seem to be serious, as they've gotten matching infinity symbol tattoos, insinuating they plan to make their relationship last. It's unclear if the pair plan to wed or have any children together, but at the least Dakota may eventually be the stepmother to Chris' two children, Apple and Moses, whom he had with ex Gwyneth Paltrow.
