Camila Cabello is clearing the air.

The 19-year-old singer took to social media on Monday to offer up her side of the story regarding her controversial exit from Fifth Harmony. Cabello calls the last five years, since the group was first formed on The X Factor, "the most important chapter of my life thus far," while claiming that at least one aspect of the group's official statement is "simply not true."

"I was shocked to read the statement the Fifth Harmony account posted without my knowing," she wrote. "The girls were aware of my feelings through the long, much needed conversations about the future that we had during tour. Saying that they were just informed through my representatives that I was 'leaving the group' is simply not true."

The remaining four members of Fifth Harmony issued a statement on Sunday announcing Cabello's 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," it read. "We wish her well."

The initial statement assured fans that Lauren Jauregui, Ally Brooke Hernandez, Normani Kordei and Dinah Jane would continue to make music together, in addition to pursuing their own solo projects.

"Just like the other girls said in their statement about their plans, I had also planned to continue with my own solo endeavors in the new year but I did not intend to end things with Fifth Harmony this way," Cabello fired back. "As sad as it is to see this chapter ending this way, I will continue to root them all on as individuals and as a group. I wish nothing but the best for them, all the success in the world and true happiness."

Over the weekend, Fifth Harmony performed together at Y100's Jingle Ball in Sunrise, Florida, while Cabello also joined Machine Gun Kelly onstage to sing their hit track, "Bad Things." Currently, the girls have just one remaining tour date listed on their website: the San Antonio Stock Show and Rodeo on Feb. 20 in San Antonio, Texas.
