The women just keep coming.
Now a new woman is stepping forward, Gosselin nanny Stephanie Santoro, to say that she and Jon also had an affair, calling the father of eight "very romantic."
Though Jon has denied being romantically involved with her, Santoro told In Touch Weekly that their fling began when Jon asked her to come over one night during her one-month employment as the Gosselin nanny.
At the Gosselin home, Jon asked Santoro to give him a massage, then proceeded to reciprocate. While they were sitting there, Santoro said Jon told her, "Well, I guess we can kiss just once."
She said he later told her, "Whatever you do, don't fall in love with me, because it's going to be impossible for me not to fall in love with you."
The pair made their way into the hot tub. Santoro said she was afraid "one of the kids was going to pop their heads out, but he told me to relax."
At one point, he got out of the tub and went into the house to make sure the kids were all asleep, Santoro said.
They moved to the apartment over the garage where Santoro said they "continued what was going on in the hot tub, and then he fell asleep afterward."
Jon's reported romantic dalliances have been scrutinized by the tabloids since his split with Kate. While Kate has been began spilling her heart out about the couple's problems, Jon has been exploring the party scene. He was photographed on yachts, living it up as his marriage fell apart.
In a recent People magazine article, Kate jokingly blamed an alien abduction for Jon's transformation from a computer technician into a rock 'n' roll jet-setter.
Recently, Jon told ABC News' Chris Cuomo in an exclusive interview that the headlines have been unfair. Magazine cover stories bashing him and praising Kate, he said, were both off-base and beside the point.
"I would say, let's finish what we got to finish and move on with our lives," Gosselin said. "And stop feeding into the frenzy."
Gosselin: 'I Didn't Leave Kate for Hailey'
In his interview with ABC, Gosselin discussed his relationship with 22-year-old girlfriend Hailey Glassman, the daughter of Kate's former plastic surgeon.
"I didn't leave Kate for Hailey. People think I left Kate for Hailey ... because of the time-frame and what they printed in the tabloids," Gosselin said. "You can't control who you love. I strongly believe that. You cannot control that. It's two people joined together."
Gosselin says Glassman is the "polar opposite of Kate."
"I feel like I love ... love her more than I did Kate," he told Cuomo.
"I get encouragement from her, I get respect from her. Two things that a man needs," he said of his new relationship with Glassman. "This is someone, I mean, like soul mate -- like people joke about that. But I'm not joking about that."
When asked by Cuomo, if he loves Kate, Gosselin replied: "I will always love Kate as the mother of my kids. But to tell you right now, at this point of what's going on, I do not love Kate."
Even before his relationship with Kate officially ended, Gosselin's charmed life in front of the cameras quickly became a life in the tabloids. A photo of Gosselin and 23-year-old third grade teacher Deanna Hummel leaving a club in April spurred tabloid headlines that he had been "caught with another woman" -- allegations which Gosselin denies.
"This was just my friend," he said of his relationship with Hummel. "I just hung out with her."
But there were more photos -- and more women. Kate Major, a former reporter from Star magazine, claimed Gosselin was her boyfriend and that the two had to sneak in sex when the kids weren't around. Another headline prompted another round of denials for Gosselin, who said his relationship with Major was not in any sense romantic.
"No romantic fling," he told Cuomo. "She tells stories."
Now, there is Glassman, the new woman in Gosselin's life, who he says he loves.
"I have so much to lose ... in this situation," Gosselin told Cuomo. "I could lose custody, I could lose my kids, I could lose -- but I feel like with [Glassman] that I'm not going to lose them. It's just going to get better."
