Are they or aren’t they? It seems they are. Sienna Miller and Jude Law showed up arm-in-arm at the Costume Institute Gala last night. Rumors started flying that they were back together last year when they both starred in different Broadway plays at the same time. In fact people were speculating about the possibility before either of them actually began their run. Just the fact that they were scheduled to be in the same city at the same time – and they’re both similar sorts who are total players – got people wondering if they’d rekindle their romance.

Sienna and Jude were engaged but broke up in 2005 when Jude slept with his children’s nanny. He blamed Sienna for it, saying she was always partying or sleeping. Jude must have had quite the good apology speech. Though to be fair this is Sienna Miller. It’s not like she requires a lot.

At least it keeps her out of the arms of Balthazar Getty.
