Yup, this is legit...not like the time she was supposed to be on Letterman and didn't.  The original guest scheduled was Kristin Chenoweth but she has been bumped in favor of Lohan.  Fresh out of the slammer, LiLo stopped by Jay Leno's studios yesterday to pre-record her appearance for tonight's telecast. No word yet on what Jay and Lindsay chatted about, but off the top of our heads, we can come up with just a few topics of conversation.  No doubt she will use this opportunity to sway public opinion in her favor and prove to the world that she is of sound mind and that her moral compass its directly pointed down a respectable, ethical path.
