Last night, Elsa took to Twitter and posted an utterly gorgeous picture of their sons, which shows their little legs and tiny feet dangling out of their nappies.
The Spanish actress also let fans in on what names she and Chris had decided to call the babies - Tristan and Sasha.
Roughly translated into English, Else said: "You are home! Tristan and Sasha came to this world on March 18 just after full moon. Full happiness."
Tristan and Sasha are Chris and Elsa's second and third children. In 2012, the couple welcomed their first child, a daughter called India Rose, into the world.
Speaking recently about fatherhood and being a husband, Thor star Chris said: "I'm just lucky. My wife is amazing.
"I'm lucky to have met someone who keeps me in check, and now we have this wonderful family."
Double trouble, but they look like total cuties!
