Margot is still hot as fuck and she has all the money and connections to help her stay that way. Look at Salma Hayek. 58, had a child, and still hot, probably through injecting the blood of children but it works. Robbie is still going to be in the 99% percentile of attractiveness after this baby.
Amy Adams is 50 now and she had her kid 14 years ago. She was plenty attractive in movies and appearances after the pregnancy. American Hustle was four years after her kid and she was smoking in that. The look could be part of her appearance for this film, but if not, she still had a pretty good 30 adult years.
I don't know man, it just seems like some serious knees too sharp weirdness.
