Sienna Miller Is Dating ‘Foxcatcher’ Director Bennett Miller

He’s caught Sienna’s attention! Sienna Miller has moved on with her Foxcatcher director, Bennett Miller.

The two have been flaunting their love at tennis matches in recent months, starting with two appearances at Wimbledon in July and then at the U.S Open on September 11 where the actress and the Oscar-nominated director, 49, caught a match between Novak Djokovic and Stan Wawrinka.

At the match, the two sat side by side and chatted with one another between enthusiastically cheering. At one point, Sienna grabbed Bennett’s arm as she watched the competitive tennis match.

Tennis matches aren’t the only place the twosome have been spotted out. The 34-year-old Brit showed off her director-turned-love interest at a Met Gala after party at the Boom Boom Room on May 2 in NYC.

At the Apple-hosted party, the couple, who a source says have been dating, hit the dance floor with Taylor Swift and Tom Hiddleston. The 26-year-old songstress was still dating Calvin Harris at the time; she and the Thor actor started dating in June, just two weeks after she split from the DJ.

“[Sienna and Bennett] were together all night,” an eyewitness told Us Weekly at the time.

Bennett directed Sienna in the 2014 drama Foxcatcher. During filming Bennett was dating Ashley Olsen, and Sienna was with Tom Sturridge.

The mom of daughter Marlowe, 4, with longtime love Sturridge, split from her boyfriend of four years last summer. Shortly after the breakup, she told Vogue, “It’s actually been the s–ttiest year.” Since then, the two exes have remained friendly.
