Madonna is one of the first celebs to jump into the Instagram video craze, and for her first post she's showing her fans that she can still "get into the grove." The 54-year-old pop icon, wearing workout gear and fingerless gloves, is seen dancing her little toned toosh off in the clip. Madge repeats the phrase "booty pop" as she does just that, and rounds out the video by declaring she is, "addicted to sweat." Judging by the massive spike in video selfies and panning lunch shots in our Instagram feeds, it certainly seemed like the launch of Instagram's new video feature was a success. In the first 24 hours after the switch was flipped, Instagram saw 5 million videos uploaded. Raf Simons' designs for Christian Dior were made for major moments. Thankfully, stars like Jennifer Lopez know when it's time to whip out a dramatic outfit.
