Twitter just launched an awesome new first tweets tool that allows users to see their own (and others') first tweets without having to annoyingly scroll back through their timeline. Of course, as soon as we saw this we just had to go back and look at our favorite celebs' inaugural tweets (it's a tough life here at PopCrush!). Take a look at Taylor Swift, Justin Bieber, Selena Gomez, Miley Cyrus and many more of our favorite stars' first stabs at Twitter.
