Locals in a countryside village in Somerset, England, received a surprise on Sunday: Scarlett Johansson
walking the streets on her way to a wedding!
The expectant actress
– who kept her budding baby belly under wraps in a belted camel coat – linked arms with her fiancé
, Romain Dauriac, as they made their way to the church where Princess Florence von Preussen reportedly
tied the knot with English aristocrat James Tollemache.
Other guests on hand to witness the couple wed included Arabella Musgraves, Olivia Hunt, Astrid Harbord and Camilla, the Duchess of Cornwall's nephew Ben Eliot, whose father Mark Shand recently passed away
after a fatal fall in New York.
Although there's no word on a wedding date of their own, Johansson, 29, and Dauriac do have a special date coming up: the arrival of their first child.
"We do different things. He's into the whole art-scene world. So it's nice, because we can enjoy each other's worlds, but we don't have our crazy conflicting schedules and all that other stuff to contend with," the mom-to-be has said of her relationship
with the French journalist.
