Let's make this birthday one to remember.

37 years old (Born on June 16, 1987)

Happy Birthday to the spectacular Diana DeGarmo—American Idol star, Broadway sensation and vocal powerhouse! From melting hearts on American Idol with your soaring voice, you've gracefully transitioned from belting out ballads onscreen to dazzling audiences live on stage.

Whether you're lighting up theaters in "Hairspray," charming fans as Dorothy in "Oz," or captivating crowds alongside Ace Young—that other famous love besides music—you make it all look effortless. Here's wishing you a birthday that's pitch-perfect (and far more fun than Simon Cowell ever allowed!). Stay fabulous as always; we've idolized you since day one—and we'll continue indefinitely!
