Theirs is the great love saga of the millennial generation - sorta - but the latest installment has left fans perplexed.

Justin Bieber and Selena Gomez dated on-and-off between 2011 and 2014, and Gomez's most recent relationship has been with Abel Tesfaye, aka The Weeknd.

However, fans are wondering whether the pair have rekindled their relationship after Bieber was spotted arriving at Gomez's house to 'hang out' the other day.

 

However, it seems that they have simply rekindled their friendship - and The Weeknd knows all about it. Reports suggest that the only reason that he wasn't there is because he is currently on tour.
