Justin Lee Collins has insisted he has never hit anyone in his life.
The 38-year-old TV presenter and comedian is on trial for domestic and emotional abuse, accused of slapping and harassing his ex-girlfriend, Anna Larke, during their nine-month relationship.
In police interviews the star gave after his arrest Collins told officers that Ms Larke, a recovering alcoholic, was possessive of him and believed he was going to go off with other women.
Ms Larke has claimed Collins attacked her in their Miami hotel room in March 2011.
Collins, speaking under oath at St Albans Crown Court, said he had only ever slapped Ms Larke to calm her down when she was self-harming, which he claimed she did, once gouging her wrists and threatening to commit suicide.
Saying ‘she had a screaming fit’ during a relapse in the hotel room, he said: “She would have episodes and I would try to calm her down.
“She was saying ‘You are going to hit me, you are going to hit me’, and I was saying ‘What are you talking about?’
“I have never hit anyone in my life. I don’t know where what she was saying comes from.
“A man came to the hotel room to ask if everything was all right.”
Collins, who shot to fame with The Friday Night Project, denies harassing Ms Larke, a former video games public relations worker.
