Selena Gomez's friends furious over Bieber reunion

Selena Gomez's friends are reportedly upset with her amid rumours that she has rekindled her romance with Justin Bieber.

The 19-year-old 'Baby' hitmaker posted a cozy photo of himself with Gomez on his Instagram account but later deleted it, reported Radar online.

It was recently reported that the 20-year-old singer-actress flew to Oslo, Norway to be with Bieber, who performed a concert there. The former couple appear to be getting close once again after going their separate ways in January this year.

"Selena's friends are furious that she's giving Justin another chance. They've been trying to warn her that he's no good for her and that she should stay away from him, but she just loves the attention he gives her.

"Selena didn't know Justin was going to post that picture on Instagram and squirmed when he did. Posting it was his way of marking his territory again and showing her who wears the pants, but ultimately he just wants to keep her happy so he immediately deleted it," said a source.

Bieber and Gomez first went public with their relationship after attending the Vanity Fair Oscar party together in 2011 but split in November 2012. They reconciled later that month but broke up again in January, 2013.
