>>15170802Those lines are from sitting down most of the day. I'd say her abs are real and can explain the picture.
>She is sucking her stomach inYou can see this from the line on the left side by her hip. Because of the angle of the photo it's not as apparent on the right side, but would be seen from a head on photo. You can also see how her belly button is further in compared to her ribcage.
>She is flexing.Obviously. She's appearing on TV. You can tell because her serratus' are visible. She's not lean enough for them to be visible at rest. That would probably be unhealthy and unrealistic for her to maintain longer than an hour or two without getting sick from dehydration.
>Her pantsThey're not high waisted, but they're tight and pulling her skin in a bit to get her abs to pop more. Common trick you see with gym girls.
Conclusion:
Britt has visible abs, most likely obtained naturally. She is doing a few tricks to get them to be as visible as possible and likely spent most of that day sitting down before going out there.
