NCIS: LA actress Daniela Ruah, 37, is the mother of two cute kids named River and Sierra.

The "Kensi" actress often shares glimpses of her private life on Instagram. For the occasion of National Sons Day 2021, she posted a throwback photo of herself and her son River.  

Daniela Ruah's son River has a famous doppelgänger

As Daniela Ruah revealed in her caption for the post, the little one in the photo was only 3 years old at the time. He's now 7. Do you think River remembers this?

River also looks quite a bit like Ruah's TV co-star Eric Christian Olsen. The hairstyle and grin certainly resemble his NCIS: LA character "Deeks."

Daniela and Eric play a couple in the crime series. In real life, however, she is in a relationship with his brother. Ruah has been married to David Paul Olsen since 2014.

And they make the perfect family of four. River definitely seems to have inherited those good Olsen genes.
