Justin Timberlake and Jennifer Aniston stopped by The Ellen Show to help deliver a surprise for her 2000th show. Aniston was actually a guest on Ellen’s first episode. She brought a welcome mat quite similar to the one she gifted the host on the show’s very first episode, which aired Sept. 8, 2003. But a door mat was not the surprise that she and Timberlake were delivering. It was also not the revelation that for a literal split second an actress other than Aniston played Rachel on Friends. And while Ellen and Timberlake would be a musical match for the ages, JT did not perform one of his famous rap montages.
