They're here!

Chris Hemsworth and his wife Elsa Pataky welcomed twin boys on March 18 in Los Angeles, and now the couple has revealed their names. Pataky took to Instagram to share a sweet snapshot of her sons, writing (in Spanish), "Already at home! Tristan and Sasha came into this world on March 18 just after the full moon. Complete happiness!"

Pataky also shared a glimpse into Tristan and Sasha's world in her official blog on the Spanish version of Glamour. In the post, the actress reveals how she prepped for the boys' arrival and shares pictures of the nursery.

Pataky, 37, and Hemsworth, 30, are already parents to daughter India Rose, 22 months.

"I think [parenthood] brings out the child in all of us," Hemsworth recently told Parade magazine. "That's what's so beautiful. It reminds you of the fascination you had with things and how you can spend hours just being with someone. It's amazing."
