Let's make this birthday one to remember.

39 years old (Born on April 17, 1985)

Happy Birthday, Rooney Mara! Hope your special day is filled with more joy (and fewer nightmares) than Elm Street. Watching you effortlessly transform from Erica Albright's razor-sharp wit in "The Social Network," to the brooding brilliance of Lisbeth Salander in "The Girl with the Dragon Tattoo" has been truly mesmerizing.

Here's wishing a fantastic actress who can convincingly hack computers and handle Zuckerberg-level breakups another successful year ahead. May your celebrations be as iconic as your portrayals; just remember—unlike tattoos, cake calories don't last forever! Keep dazzling us onscreen—you've definitely earned infinite friend requests today.
