Jake Gyllenhaal was seen last week in San Diego on the set of HBO’s pilot “John from Cincinnati,” visiting Austin Nichols his really close friend. Upon his arrival Jake was immediately escorted to Nichols’ trailer, where they spent most of the day. Austin left the trailer only to grab some grub for the two from catering tables. (The photo above shows the best friends at a Lakers game in 2006.) According to TMZ, this past Saturday, the pair was spotted in Los Angeles having a very intimate dinner at Jar restaurant. To prevent having their picture taken by paparazzi, they escaped through the kitchen’s back door. Why run if you have nothing to hide? BTW Reese Witherspoon was nowhere to be found!
