"The former X Factor judge also says she has always been very emotional."
Los Angeles, July 6 - Singer Nicole Scherzinger, who led the Pussycat Dolls from 2003 to 2010, says she couldn't enjoy her 20s.
In an interview to the Guardian newspaper, the 36-year-old talked about her loneliest time, reports femalefirst.co.uk.
My 20s were fruitful but not enjoyable. Being in The Pussycat Dolls was probably my loneliest time because I was quite insatiable. Nothing was ever good enough and I didn't know how to take a break. My 30s have definitely been more chillaxed, she said.
I'm recklessly ambitious. In America, ambition is a good thing - it's hunger, it's drive. I hate it when people use the word negatively, added the singer, who has been in an on-again, off-again relationship with British Formula One driver Louis Hamilton for six years.
The former X Factor judge also says she has always been very emotional.
She said: My nickname at school was Crybaby. Sometimes I can cry just talking because something means so much. And when I'm really hurting I just sob - a bit like someone is dying. I'm emotionally intense.
