Alyson Hannigan

I was idly browsing one of the many, many gossip sites I habitually read last night, and came across this practically unrecognisable picture of Alyson Hannigan (of Buffy Fame) which is there on the left.
And I say this because when you put it next to a photo of her from a couple of years ago (on the right), well, she looks a tad different from her appearance as the awkward geek of her Buffy days to say the least!
So beaut.ie readers, has she had some work done? Or is it just a good haircut and makeup? You tell us!
