Madonna looks like she may have joined Instagram after seven pics were posted to her account, which already has over 100,000 followers.
The pics include one of Madonna sweaty with the camera zoomed in on her cleavage and one of her sipping on a martini. In another, she shows a fake mustache.
There are a few signs that the Instagram account could be real, especially the "sweaty cleavage" pic, which is also on her official Facebook page, which has over 10 million followers.
No comment from Madonna or her camp.
