She HAS got the bloated look going on that many gals do when impregnated a month or two previously, (look at her cheeks and upper arm) but you're right to call me on that because I've zero knowledge of it being true or complete bullshit.

Whatever the reason, her previous looks are a thing of the past, IMO. I guess it's a good thing that she's planning to take her career in a different direction.
