(Cover) - EN Showbiz - Matt Damon cannot come to terms with being 40 years old.

The Hollywood actor reached the significant milestone ten days ago and is having trouble believing he is no longer in his 30s.

Matt often finds time flies because he never stops working and has a busy home life. The star raises three kids with his wife Luciana Bozn Barroso, and the pair are currently expecting another baby.

Im on the other side of the hill now, he told The Chicago Sun-Times. I wish it was a mis-print. Im more than puzzled by it. I dont feel like 40, but then again Ive been working consistently for 15 years. And I have four kids! How did all this happen?

The bemused star met Luciana while she was working as a barmaid in Miami, and admitted his fourth baby was almost as a big a surprise as turning 40.

He added the needs of his pregnant wife come first no matter what time of day it is.

First of all, we werent planning another one, he confessed. Once we got over the initial shock, we got into the pregnancy groove again. But I can tell you that the great thing about living in New York City is you can order anything online at any hour of the day. Whatever she is craving, they deliver.

Matt has just filmed Hereafter, in which he plays a former psychic who can communicate with the dead. The movie was directed by Clint Eastwood. (C) Cover Media
