"On Instagram there was a lot of negative comments after Justin Bieber commented, people were like: 'Justin Bieber is right.'"

Allie said that she was "taken aback" by Bieber's scolding because she had previously been DMing with the Canadian singer as the two had spoken about making music together when she was in the US.

She said she had plans to meet him before, but Bieber's scheduling issues saw the meeting cancelled.
