Anna Nicole to Birkhead -- Go F**k Yourself

TMZ obtained an AOL Instant Message exchange yesterday between Anna Nicole Smith and Larry Birkhead. Anna Nicole made it clear that she's not going to submit to a DNA paternity test without a fight.

The following is a precise transcript, complete with spelling and grammatical errors (but the user names have been changed):

Anna Nicole quit trash me at the casino
Larry not at a casino
Anna Nicole go f**k my mom to
Anna Nicole Yall are sick
Larry show up for the test with the baby\
Anna Nicole don't think so
Anna Nicole u wish
Larry everybody just want u to do right thing is all
Anna Nicole in your dreams

The deadline for the paternity test was today. We've learned Smith's lawyers were in Los Angeles County Superior Court this morning trying to block the test. The judge has not issued a definitive ruling on Smith's motion and so far the DNA test has not happened.
