Hollywood actress Nicole Kidman says she and Keith Urban fell "gently" in love with each other.

The couple celebrated their second anniversary on Wednesday.

Contactmusic.com reports that the Moulin Rouge star is enjoying married life with Urban and says it is much different from being married to Tom Cruise. Kidman and Cruise were married for 10 years and separated in 2000. Kidman said: "We just gently, gently sort of fell into each other. We were just two lonely people who went, 'Ah, there you are.'"

The couple are expecting their first child this summer.
