"And then there were 3," the pair added, signing the post as "Millie and Jake Bongiovi."

The baby bombshell comes just over a year after the 21-year-old Stranger Things actor tied the knot with Jake in a private ceremony attended by their closest family members.

The two went on to host another, much larger wedding last September in Italy.

"I'm one of four. He's one of four. So, it is definitely in our future," she said.

The Enola Holmes star said at the time that she wanted to continue establishing her career as both an actor and producer, but it seems she's ready to take on the next step!
