Happy 51st Birthday to the ever-charming Mark-Paul Gosselaar! It's hard to believe you've reached this milestone, but then again, you've been keeping our hearts racing for over 30 years! From "Saved by the Bell" to "NYPD Blue" and everything in between, you've aged like a fine wine and only seem to get better with time. Cheers to another year of being a total hunk and the ultimate heartthrob. Wishing you all the love and happiness on your special day. Here's to you and your timeless good looks! Happy Birthday! 🎂🎉🎈
