Poison singer Nicole Scherzinger had admitted she feels ''lonely'' after splitting from her boyfriend of five years, Lewis Hamilton.

The 35-year-old X-Factor judge, who agreed to call time on her relationship with the Formula 1 ace earlier this month due to their hectic schedules, explained that she feels lost without her former fella.

Speaking to The Sun newspaper, Nicole said: ''I don't have anyone here, I don't have my family, I don't even have any friends here. My publicist is my closest friend. It gets lonely but I'm working all the time.

''You just make those sacrifices and they made me feel so at home last year. It is hard but you always make those sacrifices and it's worth it.

 ''If I'm not doing X Factor I put myself in the studio. I also love good food, so I'm getting to explore lots of different restaurants here. I take my publicist and my assistant as my dates, literally.''

The former Pussycat Doll added that she is eager to find more permanent living arrangements in the UK: ''I'm going flat-hunting soon. I want to get a proper place.

''Last time I had an apartment in a hotel and I want to get a place with windows.''
