Hilary recently explained why she posted her recent bikini selfie on Instagram.

“I’ve never done anything like that before – my Instagram page is pretty tame. I had spent all weekend in a bikini and I was feeling pretty good. I’m just like everyone else; usually I’m not feeling so good. I [have a] love-hate relationship with my body,” Hilary shared on The Ellen DeGeneres Show.

FYI: Hilary is wearing a Rebecca Vallance dress. Sutton is wearing a Michael Kors dress.
