Model-actor Elsa Pataky says the fact that she and "Thor" star Chris Hemsworth have 'survived' as a couple amazes her. The 41-year-old model believes they are together because they are not afraid to 'work' on their relationship. Hemsworth, 34, and Pataky tied the knot in December 2010 and had their daughter India in May 2012, followed by twins Tristan and Sasha in 2014.  'We did everything very quickly - I don't know how we survived as a couple. We were married and then a year after we had kids.

It puts a lot of pressure on a marriage, but we came out good because there is a lot of love between us and we are very strong personalities but love each other so much. We make it work," Pataky told Vogue magazine. 'So I think our years together have been great. Every marriage has ups and downs - it's constant work to be in a successful marriage and stay together forever. Chris's parents have been together all their lives, and that's such a beautiful thing, and their families are so close," she said.
