Selena has admitted publicly that she got her heart broken when their romance ended.

'To me it was: I’m 18, I have a boyfriend, we look cute together, we like that,' she told W Magazine's March 2016 issue.

'Then I got my heart broken and I cared. Because people had no idea what was going on, but everywhere it was a million different things,' she explained. 'I was kind of in a corner, banging my head against the wall. I didn’t know where to go.'
