This pretty actress has hair we're all envious of! But how should she be wearing it?

We've loved Amanda Seyfried's since as far back as Mean Girls when it was long and straight, and after we saw her waves in Mamma Mia, she became a bit of a hair hero of ours. But is she better with the straighter 'do or the flowing curls?

Here she is at the GQ awards this week with pretty, tousled curls.

And here are her sleek, straight locks.

But what do you prefer? In Amanda's beauty battle should she be pulling out the straightening irons or wrapping her strands round the curling tongs?
