Aww, these little puppies just can't stay hidden for long. The Grey's Anatomy star has an aversion to waring bras and seeing as how she's relatively small-chested, she can usually get away with it since she consequently wouldn't need all that much support. But what is she going to do if she suddenly has to break out into a run again because she forgot her passport?

Now, I'm all about enjoying some secret nipple friction under the blouse from time to time, but you don't want to overdo it. She's going to end up chafed if she's not careful.
