The model, who ended her engagement with the Playboy founder days before they were due to marry, explained that women will always be interested him.
Harris said on the Kyle and Jackie O show: "There's always girls around him, there's always girls who wanna date Hef, so I'm not surprised. I'm happy for him if he's happy."
The 24-year-old insisted that she's "not dating anyone now" and praised her former fiancé.
"It was a mutual decision to call off the wedding," she said. "It was all the stress of the wedding; we were filming a show based on the wedding and it was all happening so fast. So I sat down and talked to Hef and I said, 'I don't know if this is right, should we be doing this?'
"He said, 'I don't need to get married you know, I'm only doing it for you because I thought it was what you wanted'.
"Once we talked about calling off the wedding I realised, maybe I'm not as happy as I thought. There was no argument at all - it was a mutual decision between us.
"I loved him and I appreciate him. I've not got one bad word to say about Hef."
