Much ado about Double DDs: Meghan McCain, a Daily Beast columnist and daughter of Sen. John McCain, apologized late Wednesday after posting a poppin’ TwitPic of herself that’s stirring up criticism.

The photo in question shows 24-year-old Meg in a tank top, holding a copy of Andy Warhol’s biography. he accompanying tweet referred to her “’spontaneous’ night in.”

The picture has amassed more than 67,000 viewings. After the snapshot began making the rounds, a “hurt” Megan began posting follow-up messages defending it.

“So I took a fun picture not thinking anything about what I was wearing but apparently anything other than a pantsuit I am a slut,” she wrote, followed by “what once was fun now just seems like a vessel for harassment” and “when I am alone in my apartment, I wear tank tops and sweat pants, I had no idea this makes me a “slut”, I can’t even tell you how hurt I am.”

She later added, “I do want to apologize to anyone that was offended by my twitpic, I have clearly made a huge mistake and am sorry 2 those that are offended…”
