And The Real Housewives of Orange County star, 43, said the steamy make-up was much hotter than their short-lived breakup!
"I am not going to try and deny it. Our sexual chemistry is off the chain and I find him to be absolutely irresistible," Kelly gushed.
But it isn't only the doc's bedside manners that had Kelly craving more!
She told Radar, "We realized how much we love each other. There are challenges, sure. But instead of throwing in the towel, we decided to work on them together."
As fans know, Kelly officially divorced ex-husband Michael Dodd late last year.
She moved on to Brian in January, but things took a turn for the worse in the beginning of July when their mismatched schedules became too hard to handle. As fans know, Brian is a cosmetic surgeon based in San Diego, Calif., which is a couple of hours south of Orange County.
At the time, Kelly told Radar, “He is so loving, but the distance is difficult and it just didn’t work out."
But after spending the 4th of July setting off her own fireworks at pal Ramona Singer's Hamptons beach house, Kelly learned that distance only made her want Brian more!
"He is worth it. We are worth it. Brian treats me how a man should treat a woman and we are very happy right now," she added.
