Smith took to Facebook Monday to share a picture in which she shows off her "fuller" figure in an all-black leather ensemble.
"My girlfriend sent me this pic, and I could clearly see the weight I’ve gained which is about … 8-10 pounds," Will Smith's wife wrote alongside the post. "I think I will keep it. I like being a lil…fuller;) Let's just hope it will fit in The Oscars dress."
The Hawthorne star also used her post to encourage women to feel comfortable in their own skin.
"Here's to loving our bodies by our own standards:)" she added in the caption.
