Monday was a big day for Instagram: It was announced that the photo sharing service was acquired by Facebook for the grand sum of $1 billion. And avid Instagram user Kim Kardashian expressed her enthusiasm for the deal via Twitter:
Wow Instagram sold for a billion dollars!!! Congrats!— Kim Kardashian (@KimKardashian) April 10, 2012
In fact, Kim had good reason to be excited, given that she had just learned how many devotees she now has on the site:
Kardashian's Instagram popularity comes as no surprise: She frequently uses her account to share family photos new and old. Since Monday, she's posted images of sister Khloe circa her tween years and stepdad Bruce Jenner's vintage Wheaties box.
When it comes to Twitter, however, Lady Gaga is still holding court, with more than 22 million followers (though Beliebers have given Mother Monster a run for her money, boosting Justin Bieber close to 20 million). Kim, meanwhile, trails behind with roughly 14 million followers.
