In fact, the newly-minted star of the new season of The Bachelorette calls a query about the liaison "probably the most inappropriate question ever."
"I'm normally a really open girl about these things, but I mean, it's one of those things that anybody can assume that if I had a steamy make-out session with Jason and I went in the hot tub that him and I quote-unquote did it," she said.
"We can also assume that every Bachelor and Bachelorette in the history of the show has done it with people. I think being a 30-year-old grown woman who is successful in her career and has a great background with great morals and values, people can take a look at me and who I am as a person and they're entitled to their opinion."
"I was actually waiting for that question. It's funny how it fires me up because I am doing something that's very public. But let's say I had slept with Jason. Then I don't think that's anybody's business. And let's say I hadn't. That also is nobody's business."
The hot tub hookup with Jillian was one of three close encounters Mesnick shared with the final competitors on The Bachelor in New Zealand.
He eventually said goodbye to Harris, setting up the season finale in which he chose Melissa Rycroft, only to break up with her for Molly Malaney.
Whatever happened in that hot tub - again, she's not saying - Jillian Harris harbors no ill will toward Mesnick or the aforementioned females.
