Singer's obsessed fan demands one-on-one meeting

Let's say she doesn't have Big Sean to protect her anymore but Ariana Grande is desperate for security after an obsessed fan showed up at her concert asking for a one-on-one meeting.

According to law enforcement insiders, Timothy Normandin has a bizarre history with Hollywood stars as well as Ariana and so they were on full alert when he arrived in Connecticut in March making a strange request.

TMZ reports that Normandin has had several run-ins with the 'Bang Bang' singer and has repeatedly sent her gifts including a 42.5 pound pumpkin.

He also did show up at her record company in Santa Monica which resulted in him been referred to see a psychologist.

Normandin was arrested at the concert ground for criminal trespass but was later released on a $5000 bond.
