Lindsay Lohan Vs Matt Lauer

NBC sources tell TMZ ... Lauer flew to L.A. yesterday, and showed up at Lindsay's Venice loft around 6 PM. We're told Lindsay was actually in the make-up chair when things went south. Sources close to Lindsay tell TMZ ... Lauer's team blindsided them by saying the interview would be extremely lengthy because producers were planning to put it on "Dateline" as well as "Today."

Lindsay kicked up her heels, saying she was told it would only be a 15-minute interview, and refused to sit for anything longer. The two sides began arguing -- to no avail -- and then Matt just packed up and left.
