The 30-year-old 'Toxic' singer, who is engaged to her former agent Jason Trawick, said that getting primped and preened doesn't come naturally to her, reported MTV online.
"I love my jeans and my sweats - I'm really just a tomboy at heart. So it's really hard for me to be like Kim Kardashian and be make-up and hair ready every time I go out of my house. I'm not a believer in that, you know?" Spears said.
Spears, who has two sons from her previous relationship with Kevin Federline, also said that she doesn't pay attention to gossip about her these days.
"I guess I've been under the microscope so long that I don't even pay attention to the nonsense any more. I gave up getting upset about things people make up about me a long time ago," she added.
