Selena has been given an unwanted reminder of her ex Justin Bieber – thanks to hackers who got into her Instagram account.

The singer had to temporarily take down her account yesterday after the hackers shared images of Biebs skinny-dipping in Bora Bora.

However Selena’s Insta is back up and running again – she’s the most popular celebrity on the picture sharing site.
