Let's make this birthday one to remember.

51 years old (Born on June 21, 1974)

Happy Birthday, Maggie Siff! Whether you're gracefully navigating the cutthroat world of advertising as Rachel Menken in "Mad Men," or fiercely holding your own as Tara Knowles in "Sons of Anarchy," you've always brought depth, strength, and unforgettable sass to every role. Your characters have taught us valuable lessons—like never underestimate a woman who can handle both Don Draper and Jax Teller!

Here's wishing you another year filled with captivating performances, memorable moments, and perhaps fewer dramatic motorcycle chases. May your birthday be as timelessly stylish as Rachel's wardrobe and as thrillingly unpredictable as Tara's storylines. Cheers to you!
