She’s been plagued with death threats and creepy messages from stalkers, and Emma Watson isn’t taking any chances anymore.

The beautiful “Harry Potter” actress hired a former NYPD officer to the tune of $150,000 per year to serve as her bodyguard.

And according to an insider, Ms. Watson had an incident on the set of “Noah” in which a crazed fan foiled security and approached her, and that was the last straw.

Nowadays Emma is under the watchful eye of Denise Morrone. A pal told press, “The one person Emma is never without is Denise. Emma has had problems with stalkers in the past and, because of her wealth, there is always the threat of kidnap. She pays for her bodyguard out of her own pocket and Denise accompanies her everywhere, even when Emma is out for dinner.

Denise is always there, making sure she is safe.”

“Denise is on high alert for one particular stalker who tracked Emma down on the set of her latest film. She is very discreet and very good at her job. She is always there looking after Emma, but you wouldn’t know. She makes sure Emma has plenty of space and freedom. If they are at dinner, Denise is part of the gathering, but is always on duty.”
