A popular fan theory has been floating around online since mid-2020 which claims that Betty will be pregnant in Season 5. It seems that some fans believe that Betty will leave Riverdale High pregnant and that, when the gang gets back together seven years later, Jughead will be introduced to his child.

The rumor got even more traction in late 2020 when two young actors were spotted getting COVID-19 tests on set, who, as one fan put it, "literally look like they can be bugheads kids." However, it appears that those actors may be playing the older versions of Jason Blossom and Polly Cooper's twins, Juniper and Dagwood.

While it hasn’t been confirmed, there are no signs that Betty Cooper is pregnant on Season 5 of Riverdale, but there is one cast member who is expecting a bundle of joy both on-and-offscreen. In July of 2020, Vanessa Morgan, who joined the show as Toni Topaz during Season 2, announced her pregnancy — a detail that showrunners ultimately used to help cultivate her storyline ahead of the show’s time jump.   

It’s unclear exactly how Vanessa’s story will unfold, but Riverdale creator Roberto Aguirre-Sacasa says that there are a number of other twists and turns ahead for the Fab Four and the rest of the Riverdale High crew in the upcoming weeks.
