Pregnant Margot Robbie is every inch the glowing mum-to-be as she flaunts her growing baby bump in a black bikini while relaxing with husband Tom Ackerley in the Italian sunshine.

Margot Robbie looked every inch the glowing mom-to-be on Thursday as she showed off her growing baby bump in a black bikini while on vacation on the Italian island of Palmarola.

The Australian actress, 34, donned a simple black bikini as she cheered on her son with husband Tom Ackerley and pals during the fun break.

The happy couple are spending the last few weeks as a couple before they have their first child together.

Margot really made the most of her downtime as she enjoyed a dip in the sea while the rest of her gang tried out some water sports.

Although Margot was unable to participate in jet skiing and other water activities due to her condition, she seemed to be in good spirits as she happily watched from the sidelines.

The Barbie star looked as radiant as ever as she topped up her tan in a two-piece halterneck top, with Margot sporting slicked-back wet hair from her swim.

He was also seen at one point in just a black blanket and a brown straw hat and straw bag.

Meanwhile, film producer Tom, 34, showed off his muscular frame in red swimming shorts.

Multiple sources confirmed to People magazine last month that Margot is expecting her first child with Tom.

Later, the couple was said to be relieved to announce the pregnancy news.

An insider told People: “Family means a lot to both of them, and they knew early on in their relationship that parenthood was something they really wanted.

“They’ve been keeping it under wraps for a while, but they’re happy to break the news.”

Multiple sources had confirmed the exciting news to People magazine about the couple, who met on the set of World War II drama Suite Française in 2013.
