Kim Kardashian Talks 'Selfies' and Upcoming Book Release

— -- With 27.2 million Instagram followers, Kim Kardashian is no stranger to social sharing.

In an interview with Adweek, the queen of social media spoke out about her upcoming book, which will feature selfie photography captured over the years.

"[I took] my first selfie in 1984 and that opens up the book," Kim said. "For a decade, I've carried a big digital camera, and I think it's just fascinating to see the process of what types of photos evolve. Mine started off on digital cameras, then they went to a BlackBerry and then a smartphone. There's just such an evolution of the selfie. And I captured that, I think, really well."

As for her 'ridiculous' selfies, the the reality star, 34, defended her so-called obsession -- saying that it's all in good fun.

"You have to have a sense of humor every once in a while," she said. "So many people think that taking so many selfies is just ridiculous. For me, what's so funny is I love taking pictures and posting them on social media for memories. I genuinely love the glam of life and hair and makeup and all of that, so I love just sharing my life with people -- that's who I've been.

"I live my life on a reality show. But sometimes people take it very seriously, or they think it's ridiculous. I'm kind of letting them know, yes, it is ridiculous, but it's all fun. I can look at a photo on social media and see a picture and know exactly where I was by the outfit I had on or who I was with. I take it more as a fun, emotional scrapbook that I love to look back on," she added.

Her book, "Selfish," will be released May 5.
