Let's make this birthday one to remember.

51 years old (Born on September 26, 1973)

Happy Birthday, Marty Casey! From rocking our screens on "Rock Star: INXS" to electrifying stages with Lovehammers, you've proven that true rock stars never fade—they just get louder and cooler. Your unforgettable performances still echo in fans' hearts (and ears), reminding us all why we fell for your music in the first place.

Here's hoping this year brings you even more epic moments—whether it's belting out classics or creating new hits that'll have everyone singing along. Keep shining bright, Marty; age is merely a number when you're forever young at heart—and eternally awesome on stage!
