Nicole Scherzinger says she was not able to enjoy her success in her twenties.
The 36-year-old star, who has been in an on-and-off relationship with British Formula One driver Louis Hamilton for six years, said she wasn't able to enjoy her success when she was a member of The Pussycat Dolls
"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.
"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," she said.
The former 'X Factor' judge also admits she has always been very emotional.
"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.
