"Happy 37th birthday to the one and only Jesse McCartney! Can you believe it's been 37 years since you graced us with your amazing voice and charming good looks? Time sure flies when you're having fun and making hit songs. Cheers to another year of rockin' out and bringing joy to our lives. Keep that youthful energy and killer talent alive as you enter this new chapter. May your day be full of love, laughter, and all your favorite things. Here's to 37 and fabulous! 🎉🎂🎈 #birthdayboy #JMacIs37"
