Overnight, the pair, who dated on and off from 2010-2015, was spotted kissing at Bieber's Los Angeles hockey game, which Gomez attended with her Cavalier King Charles puppy - a gift from her recent ex, The Weeknd.
Though sources close to the stars have said they are taking things slow - and are not yet officially back together - it seems they're both fine for the public to know they're dating.
“Justin is still very happy. They have had quiet date nights at home and outings to local, low-key spots. They are still catching up and just enjoy hanging out, a source told PEOPLE.
"They have learned from past mistakes and are not putting any pressure on each other. Things are much different and more mature.”
