Australian entertainer Rolf Harris told a jury in London on Tuesday there had been sexual chemistry between him and a woman who has accused him of sexually abusing her as a child.
Harris, 84, who is accused of abusing the woman for her entire teenage life, said she flirted with him and invited his sexual advances when staying at his home in southern England.
"It seemed to me that she was being very flirtatious with me," he said. "As you can imagine it was a very flattering thing for this young lady to suddenly be showing an interest in me."
Harris was speaking from the witness stand at Southwark Crown Court as he gave evidence for the first time in his indecent assault trial, now in its fourth week.
Harris faces 12 charges of indecent assault against four girls, some as young as seven or eight at the time of the offence, between 1968 and 1986.
He denies all the charges.
The court has previously heard that he first assaulted the woman when she got out of the shower aged 13. He then repeatedly abused her until she was 28 years old, the jury of six men and six women was told.
Describing another incident at his home, Harris said: "She seemed very very flirtatious and coquettish - looking at me with some sort of sexual chemistry."
Wearing a dark, pinstriped suit, pink shirt and purple tie, Harris told the jury he found it hard to discuss his affair.
"It's highly embarrassing ... I was a married man and I shouldn't have been doing it," he said as his wife Alwen watched on and his agent blew a kiss from the public gallery.
The entertainer earlier told the jury a series of rambling anecdotes detailing his rise to stardom and even sang a snatch of his famous comedy song Jake the Peg.
He demonstrated the sounds of a didgeridoo and mimed out his invention of the wobble-board, an instrument he made famous in the 1960s.
Asked whether he had ever hugged the woman as a young girl or made comments about her appearance, he said: "Yes I have. I'm a very touchy-feely sort of person. The trial continues.
