We have to say -- Hilary's body is looking hotter than ever!
In fact, she recently showed off her killer bikini bod on Instagram, revealing that she wanted to help inspire women to be confident with their figures.
"You now what, I've never done anything like that before," she recently said on "The Ellen DeGeneres Show." "My Instagram page is pretty tame. And 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 and I don't know, I was on a trip with my son and it's been 3 years since I had him. I'm like, I'm just so proud of my body and what it's done for me," she added. "It gave me the most beautiful little boy and I feel strong and powerful and I wanted to inspire other women."
