"The Dreamgirl As You've Never Seen Her," a cover headline teases. There's also a photo spread inside the magazine.

The 25-year-old singer-actress ("Dreamgirls") posed on a Florida beach in the bikini designed by House of Dereon, the fashion label she started with her mother, Tina Knowles.

The 2007 swimsuit edition continues with a music theme inside, featuring scantily clad models posing with Kanye West, Aerosmith, Kenny Chesney, Gnarls Barkley and Panic! At the Disco.

A five-page spread featuring Russian Anne Vyalitsyna was shot at the Rock and Roll Hall of Fame and Museum in Cleveland in September.

"Once the decision was made to have a music hook, one of the first settings to come up was the Rock Hall, because it's such an iconic place," said Sports Illustrated spokesman Rick McCabe. "It was a natural fit."

Vyalitsyna posed with Jon Bon Jovi's motorcycle and other Rock Hall items.

The magazine portrayed the museum with respect, said Todd Mesek, Rock Hall spokesman.
