Angela,Jamie, and J-Lo take the cake here. Despite what people from this generation say, Diana Ross was snubbed because Liza was Judy Garlands daughter...If you know anything about old school Hollywood..connections often earned you an Academy Award..Plus Diana was a solid actress. Who actually remembers that terrible ass cabaret movie anyway? While its over 30 yrs later and Diana Ross's portrayal of Queen Billie are still being talked about till this day. I love Mariah but only a stan(very few) would say glitter was a great movie. As far as Beyonce in Cadillac Records...Her acting got better.. But like any movie she plays in, its always the music I like more than her actual acting performance. Some of her best work musically are on soundtracks
