The couple had sworn off getting married in the past but now Jackson has said they might consider tying the knot, reported Us magazine.
"Marriage is important for the people it's important for, but neither one of us is particularly religious, so I don't think there's any particular push. But never say never! I don't know," he said.
Kruger had previously said, "Without sounding pessimistic I learned that I don't believe in marriage. I believe in a commitment that you make in your heart. There's no paper that will make you stay. A guy friend of mine said, and it made a lot of sense, that people should get married at the end of the road, not the beginning."
