People are speculating that this new song MAY be about Selena's BF The Weekend. Which is also confusing a lot of people because of the title, "Bad Liar", they are thinking something may be wrong in the relationship.
Well let's clear this up right now....all is well with Selena and The Weekend! As for the song being about him? Well she's not saying BUT what we do know is that the song isn't about something bad. You know those butterflies you get when you start talking to someone knew and you just can't hide how you feel about them? That is what she's talking about! Those feelings are making her so happy/excited that she's become a bad liar about hiding them.....so yeah this song could definitely be about The Weekend! Don't ya think?
