Let's make this birthday one to remember.

33 years old (Born on December 19, 1991)

Happy Birthday, Declan! From soaring "Walking in the Air" alongside legends like Westlife, Elton John and even Elvis Presley—seriously impressive stuff—to charming us all with your distinctive voice over the years; you've truly hit those notes higher than most of our birthday balloons.

Your talent just keeps getting better with age—it’s almost unfair. Wishing you yet another year filled with as much joy as we've had listening to your music (but fewer awkward dance moves from fans attempting choruses at karaoke nights). Here's hoping this birthday finds you happier than Elton's glasses collection and cooler than Presley's legendary hairdo!
