If you've yet to hear about Cadillac Records, it tells the "tale of sex, violence, race, and rock and roll in 1950s Chicago, [following] the exciting but turbulent lives of some of America's musical legends, including Muddy Waters, Leonard Chess, Little Walter, Howlin' Wolf, Etta James and Chuck Berry."

In further news, the R&B singer has recently admitted she will have at least one baby of her own with rapper husband Jay-Z, even though seeing her younger sister Solange giving birth left her "kind of traumatised," she told chat show host Ellen DeGeneres.
