Rhianna: 'I'm lonely'

Rhianna has discovered the negative aspects of fame - she finds life on the road "lonely".

Despite rumours that she is romancing fellow singer Chris Brown, the singer insists she doesn't have time to date - and she often ends up sitting in hotel rooms by herself.

She says: "It's not all honey and treacle. I've had no more than seven days off in the past 18 months. My schedule is punishing. And I do get lonely sitting around in hotels in cities I don't know. I don't have time to date."
