First Renee Zelwegger, now Uma Thurman seems to have changed her face beyond recognition.

In her latest red carpet appearance, she looks paler and suspiciously wrinkle free, as she barely smiles for the cameras.

It's led to speculation that maybe she's had some work done, like dermal fillers, botox, skin peels or eye bag removal.

But it's also being suggested her minimal make up may be responsible for the dramatic change.
