Let's make this birthday one to remember.

43 years old (Born on December 27, 1981)

Happy Birthday, Emilie De Ravin! From surviving mysterious islands as Claire on "Lost" to navigating alien drama as Tess on "Roswell," you've proven you're the queen of handling bizarre situations with grace (and a healthy dose of Aussie charm). Whether it's running from smoke monsters or dealing with extraterrestrial teen angst, your performances always captivate us.

Here's hoping your birthday is filled with fewer polar bears and more cake—though knowing you, you'd handle either scenario effortlessly. Thanks for all the unforgettable moments; may this year bring even greater adventures (preferably without crash landings or alien invasions). Cheers!
