I must say I'm not familiar with Melissa George - so I googled her. I see she has been a blonde for most of her career. However, she's gone brunette in the shot you posted. Prety girl.
But you'll have to forgive me for agreeing with Kelso - that V.V.'s much better looking. I am biased of course as I've had the privilege of meeting Vanessa and she is one of the most stunning beauties I have ever seen. (in case you haven't noticed - I'm a big fan of hers!)
Below is another photo of VV. and I think you'll agree there isn't a strong resembelance betwen the two. Beauty is of course in the eyes of the beholder.
