McCain's daughter on busty Twitter pic: I'm no slut

Meghan McCain, daughter of Republican presidential candidate John McCain, was branded a slut after posting this photo to Twitter.

Meghan McCain, daughter of failed presidential candidate John McCain has apologised over a Twitter picture that saw her labelled a 'slut' on the microblogging site.

The 24-year-old columnist for the Daily Beast website threatened to quit Twitter over the response to the photo, but then posted an apology.

"I do want to apologise to anyone that was offended by my Twitpic," McCain said.

"I have clearly made a huge mistake and am sorry 2 those that are offended."

She said that she had taken the photo herself while at home and posted it on the popular social network.

But the nasty reaction from Twitter users took her by surprise, and quickly turned into a media storm.

In another tweet under her name mccainBlogette she wrote: "When I am alone in my apartment, I wear tank tops and sweatpants. I had no idea this makes me a 'slut'. I can't even tell you how hurt I am".

In her column on Daily Beast, McCain continued on the topic.

"It's not like I was caught making a sex tape. I certainly didn't pose nude for Playboy. And I hadn't even exposed a nipple.

"Could it be it's because I have breasts? Because for those of you who didn't know, I have two. They're larger than some women's and not as big as others.

"I don't usually show off my cleavage — as I did in the photos I posted — which I will admit is not the smartest thing I have ever done. But it's just not worth the drama it caused."

The offending photo has since been removed.
