“There is a lot of power in saying I will proudly and unapologetically embrace that part of my identity for once,” Mock, who now hosts So POPular! on MSNBC, said. “The one part of my identity that I was taught growing up to be silent and shamed about.”

Mock, 32, first publicly came out as transgender in a 2011 Marie Claire article before publishing her bestselling memoir Redefining Realness: My Path to Womanhood, Identity, Love & So Much More last December.

“To own that label and to say that it is mine and I will stand here in that complicated-ness of existing as a trans woman, I think there is power in that.”

The transgender advocate also Tweeted her support for Bruce Jenner after he sat down with Diane Sawyer to reveal he is transitioning from male to female.
