Kate Winslet’s sudden and secret wedding to Ned Rocknroll, who changed his name from the more sensible Ned Abel Smith, immediately sparked rumors that she could be expecting. But despite photos of Winslet holding a tiny tummy in Hong Kong, sources tell us she isn’t pregnant. She and, ahem, Rocknroll (nephew of Richard Branson) wed in upstate New York earlier this month, in front of only a few family members and friends, including her “Titanic” co-star Leo DiCaprio.
