Let's make this birthday one to remember.

40 years old (Born on November 27, 1984)

Happy Birthday to the fabulous Sanna Nielsen! Queen of Melodifestivalen, it feels like just yesterday you dazzled Sweden and Europe with your enchanting performance in 2014. We still haven't recovered from trying (and failing) to hit those high notes on "Undo" or dancing dramatically around our living rooms—thankfully no injuries have been reported so far.

With gold-selling albums like "Stronger," you've proven there's nothing stronger than your voice—or maybe Swedish coffee. Either way, cheers to another year where you're clearly aging backwards. May your birthday celebrations be as unforgettable and timeless as your melodies! You've earned it!
