The TV presenter spoke about 19-year-old Betty Kitten's sexuality in a chat with Gaydar Radio. Ross made the revelation when asked what he would think if one of his daughters brought another girl home with them.
"Well, my eldest daughter is gay so that's a question I've dealt with on a regular basis already. And providing it’s a nice woman, I’m thrilled," he said.
"I think that's pretty much out there, she talks about [her sexuality] on her Twitter feed. As any dad really, I love my kids regardless of who they are, what they do."
He added: "Certainly, their sexuality is a) none of my business, and b) certainly none of my concern. I just want them to be good, happy, stable people and so far, all three of them seem to be that."
