Anna Oliver, who filmed the Miley Cyrus bong video used to earlier hang out with troubled teen star Demi Lovato.
Oliver has gone into hiding after she received death threats from Miley fans over Twitter; she has since deleted her Twitter account.
At one time, Oliver was close enough to Demi Lovato to be going to church with her.
According to Radar Online, Lovato and former boyfriend Joe Jonas were photographed going to church together with Oliver in March 2010.
Lovato posted many photos of herself with "BFF" Oliver on the internet, including some hilarious ones with fake mustaches that they took on a Disneyland trip with a group of friends in February 2010.
