Sienna Miller and boyfriend George Barker (aka DJ Slinky Wizard) only had eyes for each other at the 2009 US Open over the weekend.

As the rest of the crowd - including Will Ferrel, actress Rebecca Cartwright and Fall Out Boy drummer Andy Hurley - took in the on-court action, the couple joked together and shared gooey looks.
