Kristen Stewart has found herself the target of hate mail from disgruntled Twi-Hards who accuse her of leading on their beloved Robert Pattinson!

The actress — best known for her role as Bella Swan in the Twilight film franchise — has been hit with a rash of threatening letters from young fans who fear she is stringing along Pattinson, while still officially dating longtime boyfriend Michael Angarano.

A National Enquirer insider spills: “The fans love Rob, and they love the idea of Kristen and Rob romancing off-screen. But they don’t like the idea that she might be hurting their favourite young actor by stringing him along while she is still dating Michael.”

The source further reveals: “She wants them to know she genuinely cares for both Rob and Michael — and doesn’t want to hurt either. Kristen hopes fans will understand how she feels and stop sending her hate mail.”
