Pop star Christina Perri has taken out a restraining order against an obsessed fan after becoming fearful of his intentions, according to a report.

Editors at TMZ.com suggest Perri has been granted a restraining order against fan Scott Brannan after claiming he had pestered her online.

The Jar of Hearts hitmaker had allegedly become worried that Brannan intended to commit "unwanted sexual acts" against her, citing comments on her YouTube.com page such as, "I just want to love you, that's all, physically most of all".

Perri also claims Brannan has contacted her relatives and friends in an effort to meet her in person.

Brannan has reportedly been ordered to stay at least 300 feet away from Perri until a court hearing later this month (Apr14).
