Let's make this birthday one to remember.

39 years old (Born on June 13, 1986)

Happy Birthday to the hilarious and effortlessly charming Kat Dennings! From stealing scenes in "Nick and Norah's Infinite Playlist" with your witty banter, to making us laugh uncontrollably as Max Black in "2 Broke Girls," you've consistently proven that sarcasm truly is an art form. Your comedic timing deserves its own award—or at least a cupcake from Williamsburg Diner.

Whether you're rocking quirky roles like Mona in "The House Bunny," or bringing depth and humor into films like "Charlie Bartlett" and your memorable shorts, you always leave audiences smiling. Here's hoping this birthday brings fewer broke-girl moments—and plenty of cupcakes!
