Let's make this birthday one to remember.

51 years old (Born on September 26, 1973)

Happy Birthday, Dr. Luke! Ever since you made us belt out "Since U Been Gone" at the top of our lungs back in 2004, you've been crafting hits that stick like glitter—impossible to shake off and always sparkling bright.

From turning catchy beats into chart-topping anthems for pop royalty to remixing tracks we didn't even know needed a makeover—you've consistently proven you're music's ultimate doctor (no prescription required!). Here's hoping your birthday is as legendary as your discography; may it be filled with laughter louder than Kelly Clarkson’s high notes and celebrations bigger than any Billboard hit!
