In the past, 47-year-old Pitt and 35-year-old Jolie said they wouldn't marry until gay couples could do so legally, but that could be about to change.

Pitt – who raises adopted children Maddox, 9, Pax, 7, Zahra, 6, and his biological kids Shiloh, 5 and twins Knox and Vivienne, 2  with Jolie – confessed that the brood would like them to tie the knot.

He said: 'The kids ask about marriage. It’s meaning more and more to them.

'So it’s something we’ve got to look at.'

The long-time lovers still enjoy an active sex life - and Brad says they are completely honest about it with their kids.

He revealed: 'We tell the kids, "Mum and dad are going off to kiss." They go, "Eww, gross!" But we demand it.'

Pitt began dating Angelina in 2005, shortly after he split from his first wife Jennifer Aniston.

The father of six says he and his film star wife try to give their children a normal upbringing.

He said: 'Angie and I do everything we can to carve out some semblance of normalcy for them, to recreate the kinds 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.'

Pitt's most recent film The Tree Of Life, in which he plays a sometimes abusive father, received mixed reviews at the Cannes Film Festival.

But the actor told US Weekly: 'I certainly don't raise my kids the same way [as my character does].
'I am painfully aware that my actions leave an indelible mark on them in these formidable years.'
