The 'Baby' hitmaker had made little Briana's dreams come true last year, when an online campaign launched by her parents led to a meeting between the 10-year-old leukaemia sufferer and her pop icon, reported Daily Star.
The girl passed away over the weekend. "Just got news about little Briana. I was honored to meet her. I know she is up in heaven smiling. rip Briana.. Much love," he posted on Twitter. Bieber also shared a photo of the pair from their 2012 meeting.
