In early 2007, Mattel teamed up with MAC Cosmetics for the limited-edition Barbie Loves MAC line, which was MAC's most successful collection ever. The nostalgic line of bright and playful shades (at right) was inspired by Barbie but designed for grown women.

Now, Mattel turning its makeup brushes toward a younger generation. According to MediaPost, Mattel is working with Bonne Bell to develop a makeup line for girls. (Thanks to Jezebel for the tip.)

Though Mattel hasn't released any details, the collection will reportedly target buyers ages 6 to 9. The Bonne Bell products are expected to launch next year. Say Mattell, via MediaPost:

"The Barbie and Bonne Bell partnership will bring girls a fun, feminine and unique beauty experience, leveraging the unparalleled popularity of two globally loved brands," the company says in its announcement.

When I was a kid, I loved Bonne Bell Lip Smackers, and I know that little girls love playing around with makeup. But creating actual makeup designed especially for the pre-tween set just seems wrong to me. What do you think?
