Jack and James Marsden
We were seeing double on the 2017 SAG Awards red carpet when Marsden arrived with his 15-year-old son. The dapper teen looked just like a younger version of his dad — except for the platinum blonde hair, that is!
Brooklyn, Romeo, Cruz and David Beckham
Each of Beckham's boys, who are now 17, 14 and 11, respectively, look like the soccer star in their own way. (And they're all equally adept at giving good face, apparently.)
Clint and Scott Eastwood
The actor played up his resemblance to his famous father by dressing as his iconic spaghetti Western character The Man with No Name for Halloween.
Ryan and Deacon Phillippe
There's no doubt that Phillippe's 13-year-old son with ex Reese Witherspoon got it from his papa.
Ray and Jack Nicholson
The now-24-year-old is the spitting image of his legendary father's younger self.
Rocco and Guy Richie
The 16-year-old son of Ritchie and Madonna, who is pictured here with stepmom Jacqui Ainsley and brother David Banda Mwale Ciccone Ritchie, 11, favours his filmmaker dad in his sweet visage.
O'Shea Jackson Jr. and Ice Cube
Jackson Jr. looks so much like his rapper father that he played the much-younger Cube in the 2015 N.W.A biopic Straight Outta Compton.
