Lady Gaga Weight Gain: Inspires "Body Revolution," Embraces Curves in Exposed and Untouched Underwear Pics [PHOTOS]

Lady Gaga has fully embraced her recent weight gain, and the "Bad Romance" songstress sure isn't afraid to flaunt her new curvaceous figure. All the hype surrounding Gaga's added few extra pounds has even inspired the Mother Monster to start a 2013 "Body Revolution" campaign as part of her "Born this Way" Foundation. Gaga is motivated to influence others to accept and embrace their own unique selves no matter what their body shape or image, and has released a number of untouched, bra-and-underwear clad snapshots to prove it.

Lady Gaga's "Body Revolution" campaign, launched early on Tuesday, encourages all Little Monsters to accept the body they are born with, flaws-and-all. In a number of photos posted on her fan site littlemonsters.com, the 26-year-old pop star wears nothing but a lacy, pale-yellow bra and underwear set. Lady Gaga appears all natural in the snapshots, with no editing or retouching done to the images. In one photo posted on her Facebook page, Gaga stands facing the camera straight-on, with her eyes closed and her arms lying limply at her sides. She shares a link to her fan page with the message, "Body Revolution 2013: Please sign up and join a BODY REVOLUTION!" When fans click on the link they find a number of similar exposed yet strength-inspiring pics of Gaga- photo headlines include "Bulimia and anorexia since I was 15," "To Inspire Bravery," "Breed some motherfu##ing compassion," and "But today I join the BODY REVOLUTION." The photos of Gaga were snapped by photographer Terry Richardson.

As part of the "Born this Way" Foundation, Lady Gaga writes this blurb on the "Body Revolution" 2013 homepage:

"My mother and I created the BORN THIS WAY FOUNDATION for one reason: 'to inspire bravery.' This profile is an extension of that dream. Be brave and celebrate with us your 'perceived flaws,' as society tells us. May we make our flaws famous, and thus redefine the heinous."
