Actually, in my opinion, I think Nicky might have a botox injection maybe a short time before that picture is taken with Jimmy. From what I know about botox injection (not from personal experience! ) it sort of makes the muscles not responsive to the nerves, hence reduces wrinkle lines. But this also makes the muscles look stiff as it would not move where it suppose to move when a person smiles. I think that's why the face will look stiff. But then, I am no expert and I could be WRONG!
