Lady Gaga celebrates birthday with a topless Twitpic

Lady Gaga -- still on her world tour -- tweeted a provocative -- on many levels -- birthday (she turned 24 on Sunday, March 28) message for her “little monsters.”

The major buzz is that the photo looks like she might be topless. Wow, how shocking! But some people are more interested over her “communist” undercurrents.

“Last words are for fools who haven’t said enough,” is allegedly a quote from from communist leader Karl Marx, 64, on his deathbed in 1883. They were spoken to his housekeeper, who asked him for his last words so she could write them down.

Is there a deeper meaning or is it just Gaga being Gaga?
