Photos of Sienna Miller and Jude Law Going to Jonny Lee Miller's Son's Birthday Party

Sienna and Jude Hit the Birthday Party Circuit

Sienna Miller and Jude Law were both on their way into Jonny Lee Miller's son's first birthday party earlier today in NYC. The pair certainly seems to be spending lots of time together, after she was spotted bolting from photographers on her way out of his apartment yesterday. Jonny has so far been Sienna and Jude's Big Apple link — he's one of Jude's oldest friends and is currently starring in After Miss Julie with Sienna. These frequent run-ins have many speculating that Sienna and Jude are back together, but you guys just aren't into the idea.
