The couple were caught キス each other! check out the pics here on Fanpop. Went on a 日付 at I HOPE, also check out that pic online!
If he loves Selena, why wouldn't he just admit it? My guess is that he's afraid he'll loose his fans, Selena will be hated によって million of girls, & no one would によって Justin's Album.
U know how Justin always skips the 質問 "Do U have a girlfriend?" during interviews? Thats a clue beliebers!
However, If you're truly a belieber, U would be happy for him cause he's happy :)

Peace!
