Taylor Michel Momsen, turned 20 this past Friday. We first came upon this talented actress, model and kick-ass rock star, in the “Gossip Girl” series (yes, I’ve watched the entire series and loved it), where she played the cute little sister.

Then, out of nowhere, she broke that “cute little sister” image by becoming the sexy lead singer of the hard rock band “The Pretty Reckless”.

Whether you preferred her sweet and innocent look while she was playing “Jenny Humphrey”, or the goth/bad-ass look she has now; the fact remains that she is very talented, and crazy hot no matter what style she chooses to go with.

Here’s to Jenny Humphr… I mean Taylor Momsen! We wish her a happy birthday, and expect great things for her in the future. But for now, here are a few pics for your enjoyment:
