Let's make this birthday one to remember.

66 years old (Born on December 08, 1958)

Happy Birthday, Billy! From dancing your way into our hearts as Christopher Donlon in "Fame," to plotting drama-filled days in Salem on "Days of Our Lives," you've gifted audiences with unforgettable moments. We still haven't recovered from your smooth moves—and frankly, our TVs are jealous!

Here's wishing you all the stellar success and happiness you deserve today. May this next year bring even bigger stages, plenty of laughter, and scripts filled with juicy intrigue—and maybe fewer dramatic cliffhangers! Happy birthday to the one actor who still has fans shouting at their screens; keep dazzling us for years more!
