When asked if the engaged couple might hold the ceremony in Britain, Pitt said, "We could do."
"It has been such an amazing summer here, with all your events -- the Jubilee and the Olympics. I've watched everything," he added while at a screening of his upcoming film, "Killing Them Softly" at the Mayfair Hotel in London.
"We are going to do it," Pitt said, of a wedding. "We haven't set a date yet, though. We are getting a lot of pressure from our kids."
The couple confirmed their engagement in April after seven years of dating. They have six children together -- Maddox, 11; Pax, 9; Zahara, 7; Shiloh, 6; and 4-year-old twins Knox and Vivienne.
