Selena actually knows how to be like Justin and they have way more things in common, they both struggled with their families, they both know about how music and being famous works, they both left social media for awhile Bc of their health, they were both struggling with depression and anxiety. They both cancelled their tour or whatever because they wanted to focus on their health. They both had some bad moments like drugs and stuff. They have wrote music about each other when they were going through happy times and break up moments. Hailey has no idea how being famous feels like, she grew up with her dad being famous and her family being famous but her mom and dad has always stayed by her side and I don’t think she grew up with a single parent like Justin and Selena did. Hailey didn’t live in poverty like Justin and Selena both did. Literally Justin and Selena have soooo much things in common and they both can relate to each other. I bet they have so much to talk about. And anyways scooter was the one who mentioned Selena to Justin, and with Hailey it was her dad Steven Baldwin who showed up at the Today Show in NYC with her daughter to meet Justin. Justin knew Selena when he also knew Hailey. Justin chose Selena for years while he still knew Hailey as a friend.
