Can you believe this is Katy Perry?!

Yesterday we spotted the pop star clutching a cup of coffee on the set of her Proactiv shoot, and we're so happy to see that she's ditched the technicolor hair and wild makeup! Katy has been a spokesmodel for the brand since 2010, and she has stated that the skin care product helped get rid of her acne, which she's battled for years.

In other Katy news, the pop star made Barbara Walters Most Fascinating People of 2011 list, and she chatted with the TV icon about her strict Christian upbringing. "Everything I do is a bit slightly forbidden," Katy told Barbara. "When I was a little girl, I kind of thought that our world, my family's world, was the only type of world that existed. I had no idea that there was, you know, rock and roll or MTV … we had television but it was very censored. If people were about to kiss, I would never see that actual kiss. It would be changed the next second, but I didn't know that at the time."
