Pitt - who raises Maddox, nine, Pax, seven, Zahara, six, and biological kids Shiloh, five, and two-year-old twins Knox and Vivienne with Jolie - admits that the children are putting pressure on the couple to tie the knot.
"The kids ask about marriage. It's meaning more and more to them. So it's something we've got to look at," femalefirst.co.uk quoted Pitt as saying.
Pitt, 47, started dating the 35-year-old actress in 2005 shortly after he split from first wife Jennifer Aniston.
