Look at her boobs and her belly! Nipples all streched out and much darker, still has a belly pouch.
look at the last pic.
I may be wrong, but I don't think so.
I hope I am right, the other reason is that she has just let herself go!
Probably just a bad set for any number of reasons (full moon, water retention, tired, weather, bad sushi the previous day, photographer/crew personality, boyfriend issues, etc.). I lose my studly physique and bloat up after eating corn chips. There are often a few unattractive sets with all models. The face makeup doesn't help either. She looks better without any.
