Let's make this birthday one to remember.

54 years old (Born on April 21, 1970)

Happy Birthday to the hilarious Nicole Sullivan! From your unforgettable sketches on MADtv—whether it was your spot-on Britney Spears impressions or the iconic Vancome Lady—you've kept us laughing until our sides hurt. Your comedic genius and impeccable timing have truly made you a timeless treasure.

And let's not forget how you've brought countless animated characters brilliantly to life, from Shego in "Kim Possible" to Joan of Arc in "Clone High." May this birthday be filled with as much joy and laughter as you've given all of us over the years. Keep shining bright, Nicole—we adore you!
