Rihanna Admits Her "Schedule Is Punishing"

Rihanna has spoken about the low points of living such a hectic life as she promotes her music career.

The R&B star could be heard saying: "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," Rihanna adds, "and I do get lonely sitting around in hotels in cities I don't know."

The singer has also been house-hunting with her boyfriend, fellow singer Chris Brown.
