According to reports, Gwyneth Paltrow was admitted to New York's Mount Sinai Hospital yesterday afternoon. The actress was accompanied by her husband, Coldplay's Chris Martin, who was seen pushing a slumped-over Gwyn in a wheelchair. "She did not look well," a witness said. A source told Usmagazine.com that the couple were staying overnight in the hospital. What's ailing Gwyn is not known, and her rep would only say, "We are not commenting as it's a personal matter." Mysterious. Get well, Gwyn!
