Bear with me, I'm trying to be nice.....
Definitely lost weight, the face looks less puffy. That said, she's got a 8-month-old so she probably just getting back to normal now. Wonder if they did a boot camp over there? Personal trainers every day, eating well etc.
The face does look different but that could be the weight loss. Could also be botox and fillers!
Shes lost her tan, but that's probably because in summer mixed-race people do tan a lot and its middle of winter now. Same for her hair, it will look more rigid if she is straightening coily hair every day, it will need a lot of product to keep it straight. Would be nice to see her don natural hair and would set a good example for young black girls too.
I remember reading about Rochelle Humes realising that her daughters were seeing her straighten her hair every day and worrying if it was subconsciously telling them that their curly hair wasn't as good.
