Los Angeles, Dec 19 (IANS): Popular girls group Fifth Harmony has announced that singer Camila Cabello has left the group.

Remaining members Ally Brooke, Normani Kordei, Dinah Jane Hansen and Lauren Jauregui will continue the group as a quartet, reports billboard.com.

In a message posted on social media and signed by "Ally, Normani, Dinah and Lauren", the group wrote: "After four and a half years of being together, we have been informed via her representatives that Camila has decided to leave Fifth Harmony. We wish her well."

As recently as December 9, when the iHeartRadio Jingle Ball tour hit New York City, the group had announced plans to release a new album.

After forming on the second season of the American version of "The X Factor" in 2012, Fifth Harmony released two albums beginning with Reflection in January 2015. That album included "Worth it", their first Top 20 hit on the Billboard Hot 100 chart last summer.

While the 7/27 tour brought the group on their first international trek this year, Cabello had hinted at pursuing solo material through two successful collaborations.
