This is a promotional image that the Move to the Music girls did early on in their careers when they were very much presented as a band that teenage girls would listen to. Even though promotional stuff like this didn't hurt their chances of increasing their interest with teenage boys either.

Note. Brandy, the one on the far right, takes no prisoners. No little girlie swats with the pillow from her. She can bowl you over with that pillow! In the next second or so I expect to see Isabella's glasses go flying across the bed.
