Happy 40th birthday to the ultimate singing sensation, Delta Goodrem! Can you believe our beloved Delta is now part of the 40 club? It's hard to imagine because she still looks and sings like she's in her twenties! How does she do it? We may never know. But one thing we do know is that Delta has graced our ears and hearts with her beautiful voice and inspiring music for the past four decades. Here's to many more years of hitting those high notes and melting our hearts. Happy birthday, Delta! Keep shining and radiating that youthful energy. Cheers to 40!
