Lena Martinson is a favorite around here, particularly for her scalding-hot lingerie shots and glorious backside. She goes by @lenachubz for some reason on Instagram. We don't see anything especially chubby on her. And we've looked all over her. Maybe it's one of those reverse-psychology things. Maybe Lena's a bit smarter than your average Playboy Miss Social. Maybe Playboy Miss Socials are smarter than your average internet scribe. Hmmm ... we'll just have to continue our investigation by looking at more pics of Lena. Pity us.
