Why Lena Dunham's Leg is Sweeping the Internet

It's time for 'Celebrity Guess Who!' (or rather 'Celebrity Guess What').

This image has been sweeping the internet today for a very positive reason. So,  if you're thinking "I bet that's part of Lena Dunham", you'd be right. But which part? 

She captioned the below instagrammed pic with a simple: "springtime means shorteralls #nothighgap."

This simple message is just as powerful as the one she posted two weeks ago...

The actress/writer/producer captioned the above:

Promised myself I would not let exercise be the first thing to go by the wayside when I got busy with Girls Season 5 and here is why: it has helped with my anxiety in ways I never dreamed possible. To those struggling with anxiety, OCD, depression: I know it's mad annoying when people tell you to exercise, and it took me about 16 medicated years to listen. I'm glad I did. It ain't about the ass, it's about the brain. Thank you @tracyandersonmethod for showing me the light (and @bandierfit is where I bought my Florida mom inspired workout look.) #notsponsored #stillmedicated

Say what you want about the latter series of 'Girls', Lena's still the number one ambassador for body image acceptance. 

Do you love Lena's approach to body image? Is there a particular woman who inspires you?
