Gwyneth Paltrow went to Mount Sinai hospital in New York yesterday afternoon.
A eyewitness told Us Magazine, "She was slumped over in a wheelchair pushed by her husband Chris Martin. She looked not well."
Later that afternoon a bag labelled "Gwyneth Martin" was delivered to the hospital where the couple spent the night. The bag was coming from a hospital supply store.
The reason for the hospitalisation of the 35-year-old actress remains unknown. Her rep stated, "Yes she was at the hospital and is fine and now at home."
