Sienna Miller's Courtside Love Match With DJ Boyfriend - Pictures

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.

It's a less controversial choice than her last beau – married father-of-four Balthazar Getty.
