Gwyneth Paltrow was hospitalized overnight yesterday for an unknown reason according to Us Weekly.

"She was slumped over in a wheelchair pushed by [husband] Chris Martin," an eyewitness tells Us. "She looked not well."

At 6:30 p.m., a bag — labeled "Gwyneth Martin" — from NYC organic home supply store Organics Avenue was delivered.

Her publicist, said "We are not commenting as it's a personal matter," but he did confirm that she is resting at home now. I wonder what was wrong with her?
