It's been quite a week for former Secretary of State Hillary Clinton - from joining Twitter to a speech in Chicago, and even to snapping selfies.

"Having so much fun with Chelsea, taking selfies back stage. MT: @ChelseaClinton http://bit.ly/11BgawY," @HillaryClinton tweeted Friday.

Clinton and her daughter Chelsea were at a Clinton Global Initiative America event in Chicago where the former Secretary of State spoke on Thursday.

But Clinton is no stranger to the selfie phenomenon. At a State Department Dinner for the Kennedy Center Honors gala last year, Clinton posed for a selfie with actress Meryl Streep, who snapped the picture from her iPhone.

Hillary Clinton entered the social media sphere on Monday when she made her first tweet, racking up nearly half a million followers in just five days.

"Thanks for the inspiration @ASmith83 & Sllambe - I'll take it from here… #tweetsfromhillary," Clinton's first Tweet read.

And as she leaped into the age of social media this week, Clinton left an opening for her future career aspirations as she described herself as a "Wife, mom, lawyer, women & kids advocate, FLOAR, FLOTUS, US Senator, SecState, author, dog owner, hair icon, pantsuit aficionado, glass ceiling cracker, TBD…"

President Bill Clinton highlighted the selfie, noting he was left out of the picture by tweeting, "Is someone missing?"
