Britney Spears and her fiancé Jason Trawick have revealed how their relationship went from business to pleasure.
According to Trawick, who previously was one of Spears’s agents, the singer made the first move, he tells ELLE magazine in its October cover story, on stands Sept. 18.
“It was kind of one of those things where she moved, like, turned around, so we were face-to-face and then …, ” says Trawick, who became engaged to Spears last December.
But before Trawick, 40, can spill any more juicy details, his fiancée interrupts him, saying, “Okay, that’s enough information, sweetie. It was sweet, just say that.”
Spears, 30, is more straightforward when it comes to discussing her feelings toward fame.
“I guess I’ve been under the microscope so long that I don’t even pay attention to the nonsense anymore,” she says. “I gave up getting upset about things people make up about me a long time ago.”
The X Factor judge admits that balancing her career with her life as a mother to Sean Preston, 7 this month, and Jayden James, 6 this month, doesn’t always allow for high fashion.
“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 makeup and hair ready every time I go out of my house,” she says. “I’m not a believer in that, you know?”
She does admit to occasional regrets about her fashion choices. “When you do wear those sweats, you’re like ‘Oh God, I should step it up a notch,’ ” she says.
