It is unknown if the 16-year-old is definitely dating the Disney star but there is one thing Justin is sure of - how cool she is.
While he promoted his Christmas toy-collecting campaign, 'Stuff Bieber's Bus', in Atlanta yesterday, he told MTV News: 'She's really cool. She's an amazing person.'
The U Smile singer also discussed the non-stop attention he receives from fans about whether or not he is dating the Wizards of Waverly Place actress.
Bieber added: 'I think that people are always gonna be interested in my personal life... but I gotta keep some things to myself.
'I'm just having fun being a teenager.'
