The actor's 12-year-old stepdaughter Alexia is his wife Luciana's child from a previous marriage. Speaking to the Radio Times, he expressed apprehension over Luciana's teenage years.
"Like any father, I'm concerned a little about her becoming a teenager… because I know just what teenage boys are thinking," said Damon, who has three younger daughters with Luciana.
The 40-year-old went on to praise Alexia, saying: "Luckily, she is a terrific kid and the best you can hope for is that you are raising someone who has a lot of self-esteem and a lot of common sense."
