Pregnant Margot Robbie showed off her growing baby bump on Sunday as she stepped out in Santa Monica, California. 

The Barbie star, 34, kept comfortable for the outing, wearing a white crop top that highlighted her growing belly, underneath an unbuttoned white shirt.

She completed the look with a black maxi skirt and 90's style chunky platform sandals. 

The Australian beauty shielded her eyes with a pair of sunglasses and toted a black bag over her shoulder. 

The actress is awaiting the arrival of her first child with husband Tom Ackerley, 34. 

The night prior she enjoyed an outing with her friends, and donned a figure hugging blue maxi dress as she headed to The Bird Streets Club in West Hollywood, California.

The star added a black coat to her look which she draped over her shoulders, and a matching black bag.

In July an insider told People of Margot and her husband: 'Family means a lot to both of them and they knew early on in their relationship being parents was something they really wanted.

'They've been keeping it under wraps for a while but are happy the news is out.'

The couple met in 2013 while working on Suite Française, where he was an assistant director and she was in front of the camera. They married in 2016. 

'I was the ultimate single gal. The idea of relationships made me want to vomit,' she told Vogue previously of their early romance.

'And then this crept up on me. We were friends for so long. I was always in love with him, but I thought, Oh, he would never love me back. Don't make it weird, Margot.

'Don't be stupid and tell him that you like him. And then it happened, and I was like, Of course we're together. This makes so much sense, the way nothing has ever made sense before,' she said.

Margot's recent outing comes as she and her film producer partner announced last week that they were producing The Sims movie.

Robbie and Acklerley, both 34, are producing through their LuckyChap Productions company.

Much like Barbie, The Sims is rooted in an iconic franchise, with the first video game debuting in 2000 and has since sold over 200 million copies worldwide, making it one of the best-selling video game franchises of all time.

The star has continued to work throughout her pregnancy.

Earlier this month she looked positively glowing in a tight grey dress as she posed at a screening for her new film My Old A** in Los Angeles. 

She also announced an exciting new career milestone. After being an ambassador for Chanel for more than six years the Australian native is the new face of the French designer fashion house's most well-known fragrance Chanel N°5. 

The Barbie star has been an ambassador for Chanel since 2018 and was the face of Chanel Gabrielle perfume in 2019.
