Why was Selena Gomez in trouble with the police?

It’s only a few days since it was revealed that Selena Gomez and Justin Bieber were back together again, and it seems that Selena is already in trouble with the police.

Gomez was apparently hosting a party at her Los Angeles mansion, when noise levels from her “rager” became so loud that the neighbours were forced to ring police.

The police arrived shortly before midnight and warned Selena to keep the noise down or else.

One neighbour said that the noise was so loud that her windows started to rattle.

Selena shared a snap of her party earlier that evening and captioned the shot: “Tacos, live music and candles 🙂 such a beautiful night with beautiful people,”

This controversial party doesn’t come long after Selena was spotted out and about with Justin yesterday, and according to TMZ  Selena’s family and friends are not too pleased about the lovers’ reunion.
