Let's make this birthday one to remember.

43 years old (Born on June 30, 1982)

Happy Birthday, Lizzy Caplan! From navigating the treacherous halls of North Shore High in "Mean Girls" to surviving monster attacks in "Cloverfield," you've proven that whether it's high school drama or giant creatures destroying cities, you handle chaos with unmatched style and wit. And let's not forget your hilarious adventures through time-traveling hot tubs—because who else could make such absurdity look effortlessly cool?

Your captivating performances on shows like "True Blood" have left us thirsty for more (pun absolutely intended). Here's hoping this birthday brings fewer monsters and mean girls—and maybe just one relaxing dip into a non-time-traveling hot tub.
