Margot Robbie’s about to give birth to her own little Barbie or Ken … ’cause the megastar’s pregnant according to reports!

The actress and her husband Tom Ackerley are expecting their first child together, PEOPLE reported Sunday … ending a morning full of speculation after pics of Margot’s baby bump made their way online.

In the photos — published by Daily Mail — Robbie’s carefully boarding a boat in romantic Lake Como, Italy … and, her top exposed her midriff immediately getting people online talking.

PEOPLE broke their story a few hours later … saying multiple sources close to the couple confirmed the pregnancy.
