Lindsay Lohan has been treated for exhaustion and dehydration whilst working on movie Liz and Dick.

Paramedics rushed to movie stars room on Friday, but she is "fine", her spokesman said.

"Producers were concerned when she did not come out of her room and called paramedics as a precaution. Lindsay was examined and is fine, but did suffer some exhaustion and dehydration," her spokesman Steve Honig said in a statement.

"Lindsay was never taken to a hospital; reports to the contrary are false. She is resting now and is hoping to be back on set later this afternoon," Honig said.
