Lindsay Lohan was rushed to a New York City emergency room Sunday, and the actress says her health situation is related to that incident earlier this month when she reportedly bumped into a pedestrian with her Porsche.

TMZ.com reports that Lohan’s hospitalization was due to a lung infection, with what is described as a pre-existing pneumonia reportedly being aggravated by stress related to her latest arrest.

“Lindsay’s telling friends the arrest caused her so much anxiety, it landed her in the hospital — exacerbating the ‘walking pneumonia’ she’s been suffering from the last few weeks,” TMZ reports.

As previously reported, Lohan was arrested in New York after the incident involving the pedestrian.
