Megan Fox has joined Instagram. And the gorgeous actress has instantly made an impression on the social media site.

Fox, who will next be seen in a live-action version of Teenage Mutant Ninja Turtles, posted a no makeup selfie on Friday, including with it a caption that reads: `First IG selfie. Early morning no makeup.`

Let's see how long the private actress lasts on Instagram. Perhaps she'll realise that she doesn't have to say a word on it. She can just post numerous Megan Fox photos via Instagram and everyone will be happy. Very happy indeed.
