Happy 40th birthday to the ultimate punk princess, Avril Lavigne! From "Complicated" to "Sk8er Boi" to "Girlfriend," your songs have been the soundtrack of our teenage years. Can you believe you're 40 now? Time sure does fly, but you're still as fierce and talented as ever. Cheers to another decade of rocking out and living life on your own terms. Keep on being unapologetically you, because that's what makes you truly Avril-icious. Here's to 40 more years of badassery. Happy birthday, Avril! 🤘
