Cheryl Cole has stepped-up the security at her mansion in Surrey, since she recently returned from hospital.
The Sun revealed that the Parachute singer – who is still recovery from malaria – has installed cameras and heat sensors, as well as hiring private guards.
“Cheryl has made a few changes at home,” blabbed a source to today’s newspaper. “She is spending more time there than ever while she recuperates.
“She hasn’t received any threats but thought it wise to update all the precautions. She believes a more secure domestic situation will help her return to full strength sooner.”
This week it was also claimed that Cheryl is concerned for her singing voice, in case her recent malaria scare has affected her vocals.
