Hudson, 33, who met Bellamy at Coachella in 2010 and started dating each other soon after, said she was initially shocked with her pregnancy news but later became normal, reported People magazine.
"It was all very old-fashioned and proper, and we went on lovely dates. And two months later I was pregnant... Well, yes (I was shocked), but I also thought, 'This is going to be interesting'," she said.
Not only did the couple bond over their baby on the way, but Hudson's pregnancy proved Bellamy was willing to step up to the parenthood plate.
The couple have a son, named Bingham Hawn "Bing" Bellamy, together.
