The Biebster is supposedly in a relationship with pop star legend Lionel Richie's daughter Sofia Richie, but he was spotted out and about partying with a mysterious blonde in Sofia's absence.
The blonde bombshell accompanying Justin turned out to be Sofia's girlfriend, Bronte Blampied. Bronte is a full time model, so it is no wonder that Justin wants to enjoy her company.
Who do you think is hotter, Sophie or Bronte?
