Asked about her love life, the 21-year-old singer laughed and told 'On Air With Ryan Seacrest,' on Tuesday (26.08.14): ''I mean, I guess, curiosity man, it'll kill you. I don't know what to say, Ryan. Why are you doing this me?
''I'll tell you when we're not on the air. I trust you. I've known you a long time. I don't know about these millions of people listening in right now.''
A source close to the couple, who collaborated on the single, 'Best Mistake,' previously said: ''They have been friends since they made the song together.
''They have been spending more time together and recently have been getting very close. They are both doing great.''
