Nicole Scherzinger admits she is "recklessly ambitious".
The 36-year-old star, who has been in an on-again, off-again relationship with British Formula One driver Louis Hamilton for six years, wasn't able to enjoy her success when she was a member of The Pussycat Dolls, but says she is much happier these days.
The 'Your Love' hitmaker told the UK's The Guardian newspaper: "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."
But she added: "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."
The former 'X Factor' judge also admits 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."
Despite still being excited about her career, the brunette beauty is already dreaming of her retirement.
She said: "I live by the 'Aloha spirit'. My soul is in Hawaii, where I was born. It's basically having heart and compassion for others. I can imagine retiring there, wearing a muumuu [a loose Hawaiian dress] and spending my days on a paddleboard."
