Happy 41st Birthday to the endlessly talented and forever young Jack Antonoff! 🎂🎉 It's hard to believe you've been gracing us with your music for four decades now. Time really does fly when you're rocking out. May your birthday be filled with laughter, love, and all the serotonin-inducing songs you write. Keep being the coolest 40-something around. Cheers to another year of making us dance, cry, and feel all the feels. 🎶🕺 #BdayBoss #41andFierce #JackAntonoffForeverYoung 🎈🎁🥳
