Monday afternoon Gwyneth Paltrow checked in New York’s Mount Sinai Hospital. Usmagazine.com reports:

"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.

A source tells Us she and Martin were spending the night.

The reason for the hospitalization is unknown.

Her rep tells Us, "We are not commenting as it's a personal matter."

I hope she gets well soon.
