Celebuzz reported this weekend that before “bad-ass” Taylor Momsen was the eyeliner-worshipping Jenny Humphrey on Gossip Girl, she was the adorable star of a Shake N’ Bake commercial.  P.S.  She claims commercials like these are the reason for her current bad attitude and said, “Everyone’s like, ‘Wow, why is she upset and why is she so miserable about things?’ My parents signed me up with Ford (modeling agency) at the age of two. No two year old wants to be working, but I had no choice. My whole life, I was in and out of school. I didn’t have friends. I was working constantly and I didn’t have a real life.”

Check her out sans makeup and devil-may-care persona:
