Camila Cabello responded to Austin Mahone's major diss, when the "MMM Yeah" singer implied that they didn't have a real relationship! The Fifth Harmony singer totally subtweeted her ex-boyfriend, saying that it was "good to know" that they weren't actually a "real" couple.
After being shaded like that by her ex, that's probably the only appropriate response to have! And all her Harmonizers have been super-supportive, tweeting kind words with the hashtag #CamilaDefenseSquad. At this point, we're just waiting for Austin to apologize — it sounds like he really hurt her feelings.
