Jess appears fresh-faced on the cover, along with the headline, "No makeup, No retouching, No regrets".
Well, to be honest we think we can see a bit of mascara around her eyes, and maybe a smidgen of lipstick. But all in all, she's totally pulling off the natural beauty thing. She looks fantastic.
Jess decided to ditch the slap in order to promote her new initiative 'A Beautiful Me' which encourages girls and women to love their themselves as they are.
"I don't have anything to prove anymore," she tells Marie Claire. "What other people think of me is not my business."
