Sienna Miller was reportedly distraught after discovering Josh Hartnett had been hospitalised with gastrointestinal problems and rushed to see him.
Sienna Miller dashed across America to visit Josh Hartnett.
The 'Factory Girl' star was reportedly distraught after hearing the actor had been hospitalised with gastrointestinal problems and flew from Miami to Los Angeles to see him, sparking speculation they are romantically involved.
A source told gossip website X17Online: "Sienna had just 24 hours to fly all the way to Los Angeles to see Josh. She was very concerned and wanted to be sure he knew how much she cared for him."
Sienna was most recently dating 'Brothers and Sisters' star Balthazar Getty.
They split briefly last November, supposedly over Sienna's partying lifestyle, but reconciled weeks later.
However, the couple - who were first linked in May 2008 while the actor was still married - have not been seen together for several weeks.
Josh was rushed to hospital earlier this week after complaining of "excruciating" abdominal pain.
In a statement, Josh's representative Susan Patricola said the 30-year-old actor had been experiencing discomfort for months. |
