Let's make this birthday one to remember.

51 years old (Born on March 04, 1974)

Happy Birthday, Christine Baumgartner! Celebrating a woman who's perfected the art of elegance, grace—and let's face it—successfully handling Hollywood's favorite cowboy all these years. You've clearly found your secret recipe for happiness (and apparently it's tougher than taming horses or winning Oscars).

From red carpets to family adventures with Kevin Costner by your side, you've shown everyone that life just gets better when you're around. May this year bring even more unforgettable moments filled with laughter and love—because rumor has it you still manage to keep Mr. Dances-with-Wolves on his toes daily.

Here's wishing you another fabulous trip around the sun!
