Two years after their wedding, the amazing couple welcomed their second child, a daughter named Sierra Esther Ruah Olsen on September 4, 2016.
Daniela reportedly had a miscarriage in October 2015, losing her nine weeks pregnancy in the process.
Believe it or not, Olsen was there to act as a stunt double for his brother, Eric Christian Olsen, aka Detective Marty Deeks.
The two began dating not long after and had their first child in December 2013.
Well, sorry to shock you a little bit but they are both husband and wife.
The brilliant stunt performer is also active on social media platforms including Twitter, Facebook, and Instagram.
She announced on Monday that she is expecting her second child with her husband. Ruah's husband is David Olsen, and this will be their second child together.
The Instagram photo she shared to spread the good news shows her, Olsen, and their 2-year-old son, River Issac Ruah Olsen.
In the photo, the family is all working out together.
Ruah is barely showing, and she captioned the picture with the tongue-in-cheek question, "There are 4 people in this photo. " She added in this quotation from Carl Sagan to help express her excitement for the things to come: "For small creatures such as we, the vastness is bearable only through love."It may not be too surprising to learn that Ruah met Olsen on the set of If you don't watch the show, Ruah plays the inimitable Kensi Byle on the CBS series (which is going on its eighth season).
