Help me solve this mystery! (dumb question).❤︎

So this has been blowing my mind ever since I watched some TV shows about these people and noticed something. I'm in a Sherlock Holmes mood today so let's sort this out together. Three people in pictures collage below are famous actors, the guy in three pics in bottom right corner is father of two girls in other pics. BUT, one of the girls is not his biological daughter, both girls don't have the same mother by the way too. How is it possible, that a girl who was born before this guy met her mother is so similar to him? Like you can see that they are related. They tell us that he adopted her after he married her mother. Both girls are often compared saying that they DO look like sisters, however they are not blood related at all. How can his adopted daughter look more like him than his biological one??? How? Do you see this similarity too? Or is it just me? I won't tell you which of the daughters is adopted and which is biological, as it might impact your point of view, I might tell later. Just write, how do you think, which girl looks more like the dad, the one who's pictures I marked with blue hearts or the one who's pics are marked with red hearts? And do you agree that both of them look like blood related sisters and daughters of the guy? 
My version is that when he was married to mom of girl A he secretly cheated on her with mother of girl B, both of the women became pregnant in the same year, he stayed together with mom of A for a while, but when they divorced he started openly dating and married mom of B, without anyone knowing that they knew each other long before. It would cause a huge scandal if people found out that he had another kid for years before divorcing with A's mum so he decided to keep the fact that B is also his biological daughter in secret, it explains why he loved B very much, like as if she really was his daughter, and adopted her immediately. That's the only way yo can explain this mystery. 
So tell me what can you say by the photos? If
