We'll keep you updated on the birth of the twins and their names, but for now, we know (according to TMZ.com) that they were at the hospital and there was "ultra-high security in their hospital suite," with security guards at the door.
Chris and Elsa's new mini-Thor cuties join big sister India Rose, who is 22 months old. They should be plenty busy now!
The Thor star had told People magazine of fatherhood, "It makes it harder and harder to leave and go to work. I enjoy being at home a lot more than I ever have...She's the best."
UPDATE: Elsa revealed the twins' names and posted a pic of their feet on her Instagram account, writing, "You are home! Tristan and Sasha came to this world on [Tuesday,] March 18 just after [the] full moon. Complete happiness."
