These days, Christina's hairstyles are always about the curls - and it's easy to see why! They provide a much softer look for this sassy singer and really help to show off her lovely blonde locks.
Beyonce's straight hairstyle is the clear winner here. It gives her a neat and sophisticated look, whereas the curls give her too much of a wild appearance and draws too much attention away from her beautiful facial features.
Curls are a better choice for this talented singer and help to give her overall look a much softer tone and adds some extra sparkle to her long locks.
Although Ms Simpson usually looks great with any style, the curly look here is a little too over the top and the straight style gives her a more flattering finish.
