It's looking more like a blast from the past by the day, but, Selena and Justin are taking things slow.
According to reports, although the pair have been spending what looks like every waking moment together, they're not officially back together, apparently.
E! News claim that a source has said that they're 'figuring out if it will work again between the two.'
The source also stated 'Justin and Selena are seeing each other and will continue to be spending time together but haven't described it as an official couple.'
Another source said 'Things have been moving really fast but they are not officially together as of now.'
Over the past few days, the pair have been enjoying a string of dates which include bike rides, breakfast and Selena even went wearing Justin's hockey jersey to cheer him on during a game. Check out all of the snaps and fans reactions here.
