Geri Halliwell faces new stalker threat?

Geri Halliwell has reportedly increased security at her London home due to fears she is being targeted by a crazed fan.

The former Spice Girl, who split from her fiancé Fabrizio Politi last month, is said to have received nuisance phone calls and has spotted an intruder on her property.

A source told The Sun: "Geri has become increasingly concerned over recent months. This individual has been loitering around her home almost continually and it’s really upsetting and scaring her.

"Her burglar alarm has gone off a number of times when she’s been out and she’s worried about her and Bluebell’s safety."

In 2006, Halliwell told police that she thought she had a stalker.
