Sienna Miller gets her bottom grabbed by her boyfriend DJ George Baker during the 2009 U.S. Open at the USTA Billie Jean King National Tennis Center on Friday (September 4) in Flushing, Queens, New York City.

The couple watched Venus Williams pull out a win against Slovakia’s Magdalena Rybarikova despite knee problems (6-2, 7-5).

Sienna, 27, and George, aka Slinky Wizard, weren’t shy about their love in Ibiza either!
