Margot Robbie displays blossoming bare baby bump during vacation with husband

Margot Robbie showed off her baby bump during an outing with her husband, Tom Ackerley .

The Australian mega star didn't shy away from showing skin as she donned black low-rise linen pants which offered a loose fit with some extra stretch. Margot popped on a white button-down shirt, but only secured one of the buttons in the mid section, allowing the fabric to part and expose her bare belly.

The pregnant actress wore a black bucket hat and dark shades to accessorize. Margot carried a leather black bag with her in one hand as popped on a pair of slide sandals. She cradled her baby bump as she was spotted hanging out with her husband and others on the vacation in Sardinia.

Tom matched her relaxed aesthetic, pairing a plain white t-shirt with cargo shorts. He also wore a pair of black sandals and sunglasses as he stayed by his wife's side. They were seen hanging out both waterside and on board a small boat with the others. Margot made diligent effort to stay under the shade while out on the water.

The Barbie actress' pregnancy went public in July when she was spotted vacationing in Lake Como, proudly displaying her baby bump in a white crop top. This will be the duo's first child together.

Margot and Tom, who have been married for 11 years, first crossed paths in 2013 on the set of the World War II drama Suite Francaise.

They secretly tied the knot in Australia's Byron Bay in December 2016, surprising many as they had kept their engagement under wraps.

In a recent interview with The Sunday Times, Tom discussed how he and Margot manage to balance their personal and professional lives, keeping their marriage largely out of the public eye. He revealed: "It's seamless. We don't have a toggle on, toggle off. It's all become one thing."

Margot was recently caught snacking away on a train in Europe . As she and her husband headed to Edinburgh, she wore a casual outfit and chowed down. "I don't think any other travelers recognized them," a train employee told The Sun about the couple. "I pointed her and Tom out to my work colleagues, otherwise I think they wouldn't have been spotted and traveled to their final destination unnoticed. I was completely star-stuck."
