Marc Jacobs...is that you?

When I saw Marc Jacobs on the carpet at the MET's Costume Institute gala, I completely did not recognize him. Forget about slightly...completely. I had to read the credits, and even then I thought there was a mistake. And now seeing him at the CFDA awards, I still had to do a double take. I definitely cannot put my finger on this one - is is weight, is it cosmetic surgery (as said rumours), is it the hair, the wardrobe? Wow, talk about major transformation. Is it only me or does he look taller? Any thoughts on this mystery transformation?
