Matt Damon is dreading the moment his stepdaughter reaches her teenage years - because of the interest she'll receive from potential boyfriends.
The actor is dad to Isabella, four, two-year-old Gia and Stella, three months, and is also a father figure to Alexia, 12, from his wife Luciana Barroso's previous relationship.
Damon admits he's worried about how he'll cope when Alexia turns 13 - but is confident the youngster will adapt well to her teenage years.
He tells Britain's Radio Times, "Like any father, I'm concerned a little about her (Alexia) becoming a teenager... because I know just what teenage boys are thinking.
"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."
