R&R singer Rihanna has discovered the negative aspects of fame - she finds life on the road "lonely".

Despite rumors that she is romancing fellow singer Chris Brown, the Umbrella hit-maker 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."
