Definitely One Hot Tramp.

I showed this to my mom yesterday, she squealed with joy. Of course at Tony Bennett, not at Lady Gaga. She has issues with Lady Gaga because her students mainly get inspiration for fashion from Lady Gaga. And she doesn't think she's the Chanel of the fashion world now.

Well, I think the video is a delight to watch. And Lady Gaga nails this song, I never thought she had it in her. Now I know. :D
