Perry gets irritated if sleep deprived

London: Singer Katy Perry says she can be bitchy if she has not slept well.

The `California Gurls` singer, who is engaged to Russell Brand, says she gets grouchy if she doesn`t have enough sleep, but believes her fans like her "outspoken" nature, reports a news website. "I can be bitchy. Give me six hours of sleep instead of eight and I will show you the other side of me," said Perry. "I have always been outspoken and I am not easily influenced. My views are unsolicited, unfiltered and that`s why people never know what they`re going to get. There is some spice because it`s spontaneous," she added. IANS
