Miller 'rushes to visit Hartnett in hospital'

Sienna Miller has reportedly rushed to Los Angeles to visit actor Josh Hartnett in hospital.

According to X17 Online, the actress caught a flight from Miami after learning that Hartnett had been admitted to Cedars-Sinai Medical Centre with severe stomach pains on Monday.

"Sienna had just 24 hours to fly all the way to L.A. to see Josh. She was very concerned and wanted to be sure he knew how much she cared for him," claimed an unnamed source.

Earlier this week, Hartnett's representative confirmed that the star was "under observation but resting comfortably" at the hospital.

The 30 Days Of Night star was first linked to Miller last November, when they were reportedly spotted enjoying drinks together in London.
