Angelina Jolie has indicated she took a big gamble getting together with fellow Hollywood star Brad Pitt.
The couple, who met on the set of the film Mr and Mrs Smith, told Marie Claire that they entered their relationship "on a lot of faith".
Jolie, 32, already had two failed marriages behind her when she met Pitt, 43, who had just split from ex-wife Jennifer Aniston when the co-stars hit it off.
The Jolie-Pitt brood has also expanded since the pair became an item, with the couple now the parents of four children.
"Our family has grown very quickly, and we have a lot of responsibility together, and we acknowledge that we are lucky we turned out be for each other everything we'd hoped," Jolie told Marie Claire.
"We could have been very wrong, but every challenge we hit has brought us closer," she added in an interview with the magazine.
Meanwhile the actress has admitted that she has to "schedule" time to spend alone with Pitt given the demands of family life.
"We don't go to parties. We hardly ever leave the house. We try to schedule time when we're alone," she tells Esquire magazine in a separate interview for its July issue.
But if rumours are to be believed, Pitt and Jolie are planning to expand their household even further by adopting another child.
The couple are already parents to five-year-old Maddox, adopted from Cambodia; three-year-old Pax Thien, adopted from Vietnam; two-year-old Zahara, adopted from Ethiopia and biological daughter Shiloh, who was born just over a year ago.
However The Sun newspaper has reported that Jolie has now fallen in love with a child in the Czech Republic after visiting an orphanage in the capital Prague, where she is currently filming her latest movie.
