Gisele Bundchen to Tom Brady -- 'You Played the Best Game of Your Life'

Despite the fact the Patriots LOST ... and her hubby threw for a SAFETY ... Gisele Bundchen tried to comfort Tom Brady in the moments after the Super Bowl ... by LYING TO HIS FACE.

TMZ obtained video shot inside the stadium as Tom was on his way to address the media ... in which Gisele chases down Tom ... embraces him ... and whispers, "You played the best game of your life ... you were amazing."

Tom says a few words back ... and seems to appreciate the intent ... but then sends her away to talk to the press ... promising he'll only take a few minutes.

As for the REAL best game of Tom's career ... so many options:

Super Bowl XXXVI -- MVP
Super Bowl XXXVIII -- MVP
Jan. 14, 2012 -- throws for 6 TDs in a playoff game.
Oct. 18, 2009 -- throws 5 TDs in ONE QUARTER!
Jan. 12, 2008 -- completes 92.9% of his passes in a playoff game.
