Spears designs range for rocker son Sean

Pregnant pop star Britney Spears loves experimenting with her son's style so much, she was inspired to design a range of clothes for babies.

The Toxic star insists she is putting her time waiting for her second child to good use and amusing herself with 10-month-old son Sean Preston's wardrobe.

She explains: "Because I'm pregnant, I'm big, and I don't really want to get out that much.

"I go into his closet and just bleach everything!

"Preston's just like a rocker kid. Hopefully next year we'll have a fashion show, maybe at Disney World or something like that.

"We'll have them onstage, and they'll have mini-guitars. Everyone needs a mini-guitar!"
