Kate Winslet is still going very strong with her boyfriend, Richard Branson’s epically named nephew Ned Rocknroll. The couple, who have been dating for a year, had a long lunch with one other person at Isola Trattoria & Crudo Bar at Mondrian SoHo yesterday. “The pair were snuggling and seemed oblivious to anything else,” says an eyewitness. “They went through two bottles of rosé champagne. They were cracking jokes and laughing loudly.”
