Leona Lewis has fled her US mansion after fearing she was being stalked.
The Bleeding Love singer, who only moved into the £4 million Hollywood property last week, has returned to the UK after being left shaken when she was followed home from the shops by a man.
A source said: "Leona was completely unsettled by this and was pretty relieved to get back to the house safely. But when she looked out of the window later the man was still there, staring right at her. It freaked Leona out big time. She feared she was being stalked."
The 24-year-old British star felt so uncomfortable in her new home she had electronic gates and CCTV security cameras installed with a direct link to her local police station.
But despite all these new security features, friends say the alleged incident was the final straw for homesick Leona.
The source added to Britain's Daily Mirror newspaper: "Right from the beginning, the place didn't feel right. Every night Leona was on the phone to friends saying that she was lonely and not enjoying rattling around a huge house by herself.
"Friends came round to sleep over and keep her company but after she saw the man staring at her through the window Leona decided she'd had enough, and jumped on a plane back to the UK."
Now the star, who found fame on the talent show The X Factor in 2006, has asked music mogul Simon Cowell to find work for her boyfriend Lou Al-Chamaa in the US, to keep her company.
