Justin Lee Collins's former wife Karen told has told a court that they are still friends and he was a "lovely, genuine person" who was never violent to her.
Speaking with Collins looking on from the dock, she said he was a "lovely dad" to their sons Archie, seven, and Harvey, four.
Collins's friend Boyd Hilton, a journalist on Heat magazine, described him as "incredibly friendly, funny and down to earth".
Mr Hilton, who ghost-wrote Collins's autobiography and has been on several holidays with him, said: "He is obviously quite famous but is always very normal.
"He is really quite shy. He doesn't really like the showbusiness world and he doesn't hang out in that world."
Mr Hilton joined the defendant and Ms Larke on holiday when she alleges Collins bruised her face.
He said he hadn't seen any bruises and said Collins was "always very supportive of her".
