"Today is such a special day! First & foremost, it's the official 10-year anniversary of Fifth Harmony and the gratitude that I have for each one of these women and the experience of being part of something so special sticks with me to this day," Jauregui wrote on Twitter.
"Today, I'm playing @RadioCity in NY with my own music. Such an iconic venue and moment and I know it wouldn't be possible without Fifth Harmony and the amazing doors it opened for me and the incredible lessons it taught me," she continued.
"Thank you to the #Harmonizers for staying down for us after all these years. You all are magic. Thank you for making our dreams come true together and now individually❤️✨."
