"She has a huge support system and is feeling renewed now," the source added to the outlet.

Cabello and Mendes announced the news on Wednesday in a joint statement shared to their respective social media accounts.

"Hey guys, we've decided to end our romantic relationship but our love for one another as humans is stronger than ever," the statement read. "We started our relationship as best friends and will continue to be best friends. We so appreciate your support from the beginning and moving forward."
