Naomi recently pointed out the likeness between herself and her sons, by sharing all three of their yearbook photos in a line.
"The classic tomboy became the mother of these two," she wrote. "Lucky beyond words. 😍😍"
Naomi and Liev announced their seperation in September 2016, after 11 years together though they are yet to formally divorce.
“Over the past few months we’ve come to the conclusion that the best way forward for us as a family is to separate as a couple," they said in a statement at the time.
“It is with great love, respect, and friendship in our hearts that we look forward to raising our children together and exploring this new phase of our relationship.”
The pair remain friendly, regularly sharing happy and supportive photos of each other and spending plenty of time with their boys together.
