Nicole Scherzinger feels ''lonely'' after splitting with Lewis Hamilton.

The 'X Factor' UK judge - who agreed called time on her five-year on/off relationship with the Formula 1 racing driver earlier this month because of their hectic work schedules - admits she feels lost without her beau by her side and has been dining with her staff to keep herself occupied.

Speaking to The Sun newspaper, she 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 'Boomerang' singer - who is based in the US - is eager to find more permanent living arrangements in the UK.

She explained: ''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.''
