Under cross-examination at London's Southwark Crown Court on Tuesday, jurors were told that the woman flirted with the veteran entertainer, encouraging him to sit on the bed she was in as he brought her a cup of tea.It was put to the court that "sexual chemistry" had developed between them, leading to consensual sexual encounters.The woman, who was a friend of Harris's daughter Bindi, has claimed the star abused her from the age of 13, when he first assaulted her on a holiday in Hawaii.She claims there were sexual encounters between the pair until she was 28.Harris denies 12 charges of indecent assault - seven relating to the woman.His defence barrister Sonia Woodley QC said the girl became jealous after she and Bindi drifted apart when the Harrises moved away, and also because of Bindi's friendship with another girl.Ms Woodley said on one occasion the woman actively flirted with Harris, guiding him to sit on the bed she was in. She said: "You and Bindi were drifting apart, partly because of the distance between where you both lived and partly, I suggest, because of your jealousy over her friendship (with another girl)."The barrister added: "I suggest that because you were jealous over Karen, you flirted with Rolf Harris. You grabbed his elbow, guiding him to sit on the bed."The woman was also asked about another alleged assault when she stayed at Harris's Berkshire home for a second time.Ms Woodley said: "There was a second occasion when you came over to stay the night and once again he brought you a cup of tea in the morning. There was sexual chemistry between the two of you."The woman replied: "No, no sexual chemistry at all."The barrister suggested that there was, that one thing led to another and a sex act took place.The alleged victim said: "No."Earlier the court heard that the woman's diary of the holiday when she claims the abuse started showed "no hint of unhappiness", with her saying she had a "great" day with the entertainer and his family.The alleged victim was taken through diary entries from the trip to Hawaii in 1978, where she spent two full days.Ms Woodley asked her: "No mention in the diary or any hint of anything which had happened to you at the hands of Rolf Harris, is there?"The woman replied: "I wouldn't have put it in the diary."Her entry for the first full day there said: "Today was great because we went on the beach and went swimming."On Monday the alleged victim told the court that she started drinking in her early teens, and would drink gin to help control panic attacks and anxiety if she knew she was likely to see Harris.She said she had hidden the symptoms of her panic attacks, such as sweating and shaking, so nobody would know.The trial continues.
