Simpson 'could do splits while pregnant'

Ashlee Simpson has revealed details of her pregnancy.

The singer, who gave birth to her son Bronx ten months ago, explained that she remained extremely flexible, Us Weekly reports.

"I could do the splits when I was nine months pregnant," she confessed. "I could put my leg over my head still. I used to be a ballerina."

Simpson also admitted that she is already thinking about Bronx's teenage years.

"I'm definitely going to lay the boundaries down," she claimed. "It's different for a girl than with a guy, so I think we'll have to grow together and be able to lay the boundaries. But with Bronx, there will be a curfew and all that.

"I don't want him to grow up in the middle of Hollywood."
