Let's make this birthday one to remember.

48 years old (Born on January 09, 1978)

Happy Birthday, AJ McLean! Another year older, yet your dance moves remain timeless—just like our endless attempts to nail the choreography from "Everybody (Backstreet's Back)." Your iconic voice and style have kept us singing along for decades; clearly, age is just a number when you're still rocking stages worldwide.

From dominating charts with the legendary Backstreet Boys to inspiring fans through your solo projects and heartfelt openness about life's ups and downs—you've truly shown that authenticity never goes out of style. Here's hoping this birthday brings you as much joy as you've given millions around the globe. Keep being larger than life!
