News of Anuel and Karol's split came in mid-March, but the couple took to their social media to confirm and address their breakup in late April.
“If just accepting it is hard enough, imagine having to do it in front of millions of people,” Karol wrote in Spanish on her Instagram Story at the time. "For a long time we tried to keep our relationship away from social media in order to protect ourselves. We never used our relationship for marketing purposes, not today, not even almost three years ago when we started [dating]."
"We were two people with public lives that wanted to have a normal relationship just like another other and that's the reason why we never hid our feelings and went public with our relationship," she continued. "The incredible things that happened to both of us, personally and as artists, were a blessing and a result of our beautiful love."
