Lena Headey, who plays Cersei Lannister, and Jerome Flyn, who takes on the role of Bronn, are "not on speaking terms" but it's unsure why.

"Jerome and Lena aren’t on speaking terms any more and they are never in the same room at the same time," a member of the show's crew told the Daily Telegraph.
