We’re told the two actors — who have been together for about four years — are gearing up to welcome a baby, though details like the due date and gender of the child are still under wraps.

The timing comes during a particularly busy stretch for both stars … Sebastian has a packed year ahead with the upcoming release of his film “Fjord” … along with the highly anticipated Marvel installment “Avengers: Doomsday.”

Annabelle has a couple big projects on the horizon as well. She stars alongside Jason Statham in the action film “Mutiny” — slated to hit theaters in August — and she’s also set to appear in Netflix’s “Unabomb,” a project about the Unabomber, Ted Kaczynski.

We’ve reached out to reps for Sebastian and Annabelle for comment … so far, no word back.
