The 23-year-old singer, who split from Scottish DJ Calvin Harris in June after a year of dating, said she finds love confusing, reported Contactmusic.
"I think love is really incredible. Some women are obsessed with it and I'm fascinated with it. I think I'm fascinated with love because no one understands it, it's something that you're not supposed to understand, there's no rule book to it and that's what I love about it," she said.
The 'Black Widow' hitmaker, who previously confessed Harris was her first love, insists she has no regrets about her past romances.
