The 'Other Side' singer - who has been dating the former 'American Idol' winner for two years - admits it takes a lot of ''confidence'' to go out with his pop star girlfriend, but he isn't intimidated by her fame.
He told Cosmopolitan magazine: ''Going out with a woman as successful as Jordin takes a lot of confidence for a guy. You have to be sure in yourself to deal with it. I feel I can still be that protective figure without feeling insecure about what she does.''
The 23-year-old star reveals that he was something of a womaniser prior to his relationship with Jordin, 23, but suffering a broken neck during tour rehearsals in 2012 helped him put everything - particularly his romantic life - into perspective.
He explained: ''Before the accident, I was more reckless in relationships. I was a guy in my early twenties having fun. I wasn't really looking for love, but my injury woke me up.
''Jordin and I had been friends for a long time and I definitely liked her. The injury made me pay attention - it was like someone saying, 'Hey, wake up!' ''
The 'In My Head' hitmaker insists his girlfriend is ''the one'' and hopes to one day tie the knot with the singer.
He added: ''Marriage will happen at the right time.''
