Following numerous reports the two singers struck up a romance earlier this year (14), Cabello finally confirmed the rumours during an appearance on U.S. late night talk show Watch What Happens Live earlier this month (Nov14).
Mahone even gushed about their relationship in the most recent issue of Teen Vogue, saying, "She's an amazing girl, and we have the best time together."
However, just weeks after going public with their relationship, Cabello revealed on Monday (24Nov14) that they have called it quits.
During a new radio interview, Cabello admits, "We're actually not together anymore. It happened just recently, but hey, things happen."
Mahone has been previously linked to singers Selena Gomez and Becky G.
