True Lovebirds: Keith Urban & Nicole Kidman

This summer, Keith Urban and Nicole Kidman will celebrate their ninth wedding anniversary. And if the video (below), that Keith shot on the way to the Grammy's Sunday night is any indication, their union is still filled with bliss.

Keith and Nicole were married June 25, 2006 and it wasn't easy in the beginning. Keith checked himself into the Betty Ford Center for rehab less than four months later. Nicole stood by him and the couple had their first child two years later. In 2010, the couple had another daughter, this time via a surrogate mother.

I love the spark you still see between Keith and Nicole. Whether it's her hand on his chest in the above photo or playing around in the video, their love appears strong. Happy Valentines Day!
