Camila Cabello is ready to fly solo…

The 19-year-old Cuban-American singer and member of Fifth Harmony has left the all-girl group.

In a message posted on social media and signed by “Ally, Normani, Dinah and Lauren,” the group writes, “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.”

The remaining members, Ally Brooke Hernandez, Normani Kordei, Dinah Jane Hansen and Lauren Jauregui, state that they will continue the group as a foursome.

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. Kordei told radio personality Elvis Duran, “2017, it’s going to be popping,” and Jane Hansen added, “The third album is definitely going to be so lit. We’re really excited.”

Fifth Harmony was formed by Simon Cowell on the second season of the The X Factor US in July 2012. In January 2013, they signed a joint deal with Syco Music, owned by Cowell, and Epic Records, L.A. Reid‘s record label, after finishing in third place on the show.

To date, The group has sold 424,000 albums, 7 million digital songs and earned 1.6 billion on-demand streams in the U.S., according to Nielsen Music.

Their honors include three MTV Video Music Awards, an American Music Award, a Billboard Women in Music award and seven Teen Choice Awards.

In the last two years, Cabello released two singles which reached the top 20 on the US Billboard Hot 100: “I Know What You Did Last Summer” with Shawn Mendes in 2015, and “Bad Things” with Machine Gun Kelly earlier this year.
