The translation of Elsa's caption in the E!News report reads: "They are already home. Tristan and Sasha arrived in this world 18 March just after the full moon. Complete happiness!!" The Instagram post has also confirmed the official date that Elsa Pataky gave birth to the twins.

"An original report from TMZ claimed that Elsa checked in to Cedars Sinai Medical Center on Thursday, March 20 to give labor. However, Elsa's caption states that Tristan and Sasha were actually welcomed into the world on March 18," the Hollywood Life report noted.

In the March 25 blog post for Spanish Glamour, Elsa Pataky gave advice to the readers who are mothers that they should take pleasure every precious moment with their children. "Enjoy every second with your baby because it is the most wonderful thing of the world," the actress shared.

Newborn twins Tristan and Sasha Hemsworth join their big sister, India Rose, whom the happy couple welcomed in May 2012. The "Thor" actor and his wife have not given any comment yet on why they chose the names Tristan and Sasha for their boys whether there was a deep meaning to it.

With their first born child, India Rose, Chris Hemsworth revealed in the past that he and his wife always liked the name India. "I always kind of liked Indie or Indiana for a boy and she like India. We sorta went, 'Oh, well, whether it's a boy or a girl that will decide.' It just seemed to fit," the 30-year old actor shared.

In June 2013, Mr Hemsworth also admitted to the entertainment Web site that being a father made him change "for the better." The actor explained: "It puts things into perspective."
