Rihanna: "Sometimes I'd Just Like To Sit In Corner By Myself."

Sultry songster Rihanna hates having to pretend to be a 'bubbly person' all the time. RiRi revealed that she feels forced to put on a happy face when she's on the road, even when tired and miserable:

"I love what I do but, yes, this stuff does start to take its toll on you. Sometimes you get really miserable and on the edge, but people don't know why you're acting like that.

You always want to be kind to people, so you're forced to be a bubbly person, but, to be honest, sometimes I'd just like to sit in a corner by myself and be quiet."
