Beyonce is not really an actress, she just gave it a go. Beyonce is more musically inclined whilst Jennifer Lopez is an Actress. Jennifer has been acting all her life, and it is no comparison to Beyonce whatsoever, as she has no proper acting experience. Jennifer Lopez was born an Artist and has also been dancing and singing all her life. It's in her veins, now she is definetly the winner from all perspectives on here.
