JOIN USThe 47-year-old, who started dating Jolie, 35, in 2005 shortly after he split from first wife Jennifer Aniston, said that the children ask about marriage, forcing them to think on the same lines, reported Femalefirst.
"The kids ask about marriage. It's meaning more and more to them. So it's something we've got to look at," Pitt said.
Despite their large family, the actor insists he and his 'Tomb Raider' star partner get plenty of opportunity for intimate time and don't like to hide it from their children.
"We tell the kids, 'Mom and Dad are going off to kiss.' They go, 'Eww, gross!' But we demand it," Pitt said.
The 'Tree of Life' actor also tries to give his children as much of a normal upbringing as they possibly can, considering their parents are huge film stars.
"Angie and I do everything we can to carve out some resemblance of normalcy for them, to recreate the kind of moments that were special for us.
"It's not unusual for the kids to be covered in paint. We have mud fights. It's chaos from morning until the lights go out. We're hunted, our kids have to live behind a gate. Outside, there are people with cameras. But I'll take the trade-off," Pitt said.
