I just found this video on youtube:
At about 1:26 she takes off her dress to reveal what looks like latex bloomers and a matching top. Pretty cute IMO. Normally I wouldn't think anything of it but from her twitter she seems to also like pacifiers and footies. Then again, maybe it's all an act, but for some reason with her I don't think that is the case.
P.S. Conan FTW!
