Camila Cabello is breaking away from Fifth Harmony.
The band released a statement on social media on Sunday revealing the news of Cabello's unexpected departure.
"After 4 and a half years of being together, we have been informed via her representatives that Camila has decided to leave Fifth Harmony," the statement reads. "We wish her well."
"You Harmonizers have been there with us since the beginning, you've supported us, you've rejoiced and cried with us, you've grown with us, and with your love and support we will continue on," the statement continued. "We are four strong, committed women who will continue with Fifth Harmony as well as our solo endeavors. We are excited for our future, and we can't wait for what the new year brings."
Hours before the news was announced, Cabello appeared on stage with the other members of Fifth Harmony for a live performance at Y100's Jingle Ball 2016 in Sunrise, Florida. Cabello later joined Machine Gun Kelly for a performance of their hit track, "Bad Things."
Earlier this year, ET caught up with the group following the release of their sophomore album, 7/27, where they addressed break-up rumors that had plagued the band ever since Cabello collaborated with Shawn Mendes on the single, "I Know What You Did Last Summer."
"Regardless of everything that's been going on, that's always been the focus, Fifth Harmony," Dinah Jane Hansen told ET. "Fifth Harmony is definitely our first love... it's always been the foundation of everything." Check out the video below to hear more.
