Margot Robbie made sure she gave her fans a really good time when she treated them to a round of drinks at The Ivy Chelsea Garden on Friday.

The actress, 34, who is pregnant with her first child, was joined by her husband Tom Ackerley at the restaurant as they treated diners to their Papa Salt Coastal Gin.

The Barbie star was filmed mixing with staff and waving to the crowd as she enjoyed the stunning heatwave. 

As she stood at the front of the crowd, she said: 'We made this gin for you to enjoy in the sun, with friends, so this is the perfect setting.'

Before adding: 'Enjoy your drink on us. Have one for me! Cheers!' 

 The Barbie star proudly displayed her small, but visible baby bump in a black crop top and oversized blazer which she paired with some stone wash baggy jeans and open toe sandals.

She left her blonde locks down and finished her look with a pair of dark sunglasses to shield her eyes from the blazing sun. 

Her husband Tom, an English film producer, actor, looked equally as stylish in some beige jeans and a tucked in white T-shirt.

Margot, along with her husband and three best friends Charlie Maas, Josey McNamara and Regan Riskas are the founders of Australian-made-and-owned, Papa Salt Coastal Gin.

Holding a peach coloured drink in his hand, Charlie added: 'I hope you all have a 'papa salt paloma' in your hands.'

'We're the founders of papa salt and this is just a new menu here at the Ivy and we figured we'd buy y'all one so you can try it.'

 The drink contains papa salt gin, capi grapefruit soda, and a hint of rosemary. 

At Wimbledon, Margot and her husband were spotted drinking the 'papa salt paloma' from cans that are under 100 calories each - with Margot opting for a non alcoholic  'mama salt' drink.

The couple met in 2014, married in 2016 and are co-producers on a number of projects, including Hulu's Dollface, through their production company LuckyCap Entertainment. 

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

'I was the ultimate single gal. The idea of relationships made me want to vomit,' she told People 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

They started dating the following year in 2014 and got married in 2016.

'The most helpful thing I've learned from other couples in this industry is that you don't go more than three weeks without seeing each other,' she told The Daily Telegraph in 2016.

'Being in a long-distance relationship can be really hard when you don't see the light at the end of the tunnel. It can mess with your head, so the three-week rule is key,' she added.

The couple keep their relationship largely out of the public eye and didn't walk the red carpet together until 2017, almost a full year after their wedding.
