Our X17 photog Josh, who was smashed into by Ms. CrazyPorsche (not Ellen, the woman you'll see at the end of the video), will be interviewed tonight on Extra -- check it out!

Here's exclusive video of just moments after Ellen's crash on Friday and here's how it went down ... Guy in a Honda, Ellen in her Porsche with her Portia, our photographer and his girlfriend, all stopped at the red light at Laurel and Sunset ... moments later, another woman (check her out at the end of the video) slams her Porsche into our guy (check out the trunk of his car) and his car pushes forward into Ellen's.
The producers of Ellen's show have already contacted our photographer and asked him to appear on the show to give his account of the accident ... we'll keep updated.
