Sienna Miller Sienna Miller Sienna Miller JEANS STRIPED SHIRT SUNGLASSESSienna Miller flew to Los Angeles from Miami and checked into the Sunset Tower hotel to visit Josh Hartnett as he recovers from his recent health scare, X17online has learned exclusively.

Josh was taken to the hospital in an ambulance earlier this week suffering from what his publicist describes as "gastrointestinal problems."

"Sienna had just 24 hours to fly all the way to LA to see Josh," a friend tells X17online. "She was very concerned and wanted to be sure he knew how much she cared for him."

Looks like Sienna has finally moved on from Balthazar Getty!!!
