Chris Hemsworth and his wife, Elsa Pataky, have revealed their newborn twins’ names as Tristan and Sasha. The mother of three shared the names in a post for her blog on the Spanish version of Glamour.

Pataky, 37, wrote “You are home! Tristan and Sasha came to this world on [Tuesday,] March 18 just after [the] full moon. Completehappiness.”

The actress and her 30-year-old husband welcomed the twins a week ago in Los Angeles, joining big sister India Rose, 22 months.

Pataky also shared the sweet message on her Instagram account, where she also posted a picture of two sets of baby feet.

Hemsworth previously opened up about fatherhood to People, saying, “It makes it harder and harder to leave and go to work. Being a father is certainly a task. But the best one that I could ever ask for.”

She added, “You have to make an effort and try to stay together as much as you can. If we start splitting and doing other things it’s not going to last.”
