Casey Anthony calls Caylee "the little snot head" in instant messages to her ex. Read the shocking transcripts.

We're getting a look at instant messages Casey Anthony sent to ex-boyfriend Tony Rusciano. In the IMs, Rusciano never calls Casey's three-year-old daughter Caylee Anthony by name, only referring to her as "the offspring." Casey, in turn, callously calls Caylee "the little snot head." Check out the transcripts.

She gives Tony a litany of excuses of why she can't come over ... mainly running commentary about her nanny's whereabouts and her being a no-show.

Then, at 7:20 p.m.:

casey o marie: I'm sad. I've been sad all day. shit, I've been sad for days.

Ironically, at 7:37 p.m., she says:

casey o marie: you know what you're getting into with me, and i'm sorry, caylee has to come first, my job, a close second. i can only take so much time from that for anything else.
nyitaliano3: I understand but understand my point. i can't see someone once every 3+ weeks and say we're dating.
