Let's make this birthday one to remember.

51 years old (Born on January 23, 1974)

Happy Birthday, Tiffani Thiessen! From stealing hearts as the unforgettable Kelly Kapowski at Bayside High to turning heads and causing drama as Valerie Malone on Beverly Hills 90210—you've always known how to make an iconic entrance. Your sweet yet sassy persona defined a generation’s teenage memories.

Even nowadays, your timeless charm shines brighter than Zack Morris's neon wardrobe. Whether cooking up laughs or bringing warmth into homes with your delightful personality in "Dinner at Tiffani's," you continue being fabulous beyond bedazzled jean jackets of the '90s. Wishing Hollywood’s ever-classic star endless happiness sprinkled generously with nostalgia—cake beats detention any time!
