The mother-daughter team were joined on the outing by Chris' TV actor brother Luke Hemsworth.
Luke, who is Chris' older sibling – is well placed to advise the couple on the joys of looking after numerous children – since he himself is a father-of-four.
In a recent interview with HELLO! Magazine's sister publication, HOLA! Elsa revealed the couple's surprise when they realised a double arrival was on the way.
Elsa, pictured with daughter India said she and chris were "in shock" when they found out she was expecting twins
"We weren't expecting it at all, and we were in total shock," she told the magazine. "On one hand there was the excitement of, 'there are two!' and on the other: 'how are we going to manage?'
"It's a bit of a shock, but we're very happy, we think we're going to enjoy the experience, it's going to be fun and incredible, because the relationship between twins is very special."
After India was born, Elsa confessed she would love to have a boy next, to have one of each. But does she know if a little prince is on the way?
"I don't know," she told HOLA!. "I don't want to know the sex of the babies so I don't get obsessed. Since there are two, there's more chance of a little boy arriving, I hope so, it would be great."
The actress and her handsome husband enjoyed their last red carpet event before becoming parents again when they attended the Oscars. Elsa looked radiant in a glittering turquoise Elie Saab number with a drop-waist that showed off her bump to full effect.
