Celebrity Birthdays, January 23

Happy birthday to Tiffani-Amber Thiessen and Mariska Hargitay!

Tiffani-Amber Thiessen, 38
Tiffani-Amber Thiessen may have reached her peak as Kelly Kapowski in 90s hit Saved By the Bell, but don’t count her out yet. Since starring alongside Mario Lopez and Mark-Paul Gosselaar, the Long Beach, Calif. native has starred in several other hit TV shows including Beverly Hills, 90210, Just Shoot Me, and What About Brian. You can currently catch her as Elizabeth Burke on USA Network’s White Collar. But she’s not just good lucks. Back in her high school years, Thiessen was named Valley Professional High School valedictorian her senior year. And if you’re still not a fan after that, well it probably really doesn’t matter because she’s still got Justin Bieber.

Mariska Hargitay, 48
Mariska Hargitay is probably one of the sexiest cops on TV, but before she was investigating traumatic cases on screen as Detective Olivia Benson on NBC’s Law and Order: Special Victims Unit, she experienced her own shocking family trauma when she and her two brothers were involved in a car accident when they were younger that killed their mother. She was only three years old and says she doesn’t remember a thing. But that didn’t prevent Hargitay from succeeding in life, both in her acting career and academics. The actress majored in theater at UCLA, but dropped out before graduation to pursue her acting career. She also speaks four languages: English, Hungarian, French and Italian. And on top of all that, Hargitay has one of the most successful marriages in Hollywood. She and husband Hermann have been married since 2003 and have three children together.
