Have anybody an explanation what happened to the old "authentic" Melinda Gates?

I drop 2 links because I'm not that good to make click-and-see videos here in the board…

1st link is an video where you see what i think is the authentic/original Melinda Gates

2nd link is a video where you see the new / transformerred Melinda Gates.

I ask you, anons, to see it yourself and maybe you have the same idea as i do; 2 different people that are Melinda Gates:

Do I see ghosts you think? Please let me know. I think however these are different people but i cant explain and am looking and curious for any explanation. If you think I'm wrong, please let me know also.
