Gwyneth Paltrow was in a dancing mood after her hubby Chris Martin’s Coldplay concert Friday. Paltrow was spotted at LIV at the Fontainebleau Hotel, “holding hands with Chris as they walked in,” said a spy, “they were very affectionate.” She immediately hit the dance floor with a girlfriend. “She was dancing for 30 minutes straight, before returning to a table,” the spy said. Martin, who’d just performed at the American Airlines Arena, was starving and instead had “food delivered from Scarpetta.”
