A person thought to be a royal aide was spotted going into the back of St. Mary's hospital carrying clothing and a car seat, leading to speculation that the royal baby may be making his debut any minute.
Prince Charles hinted to the media that the baby might be coming soon, saying that he is "marvelous" but that they would see for themselves shortly.
Staff members carrying a hanging bag into the hospital were rumored to be accompanied by Amanda Cook Tucker, Kate's hairdresser. The Palace has since denied Tucker's presence there.
Sources at The Guardian have said that the duchess may stay one more night in the Lindo Wing of St. Mary's, which has amenities including satellite TV and a personal chef -- although Prince William and Kate ordered pizza to the wing the evening after his birth.
London got the first rain it has had in weeks, which prompted the palace to announce that the couple would not leave the hospital before 6 p.m. local time, and potentially not until Wednesday morning.
