The brother of the alleged other woman at the center of reality TV dad Jon Gosselin's reported affair said he's overheard the pair and that the two would "stay locked away like two teenagers" when they were together.
"She's a nice girl, not a homewrecker," Jason Hummel, the sibling of the purported mistress, told Usmagainze.com. "He is a bad liar. This isn't healthy for her. But she is refusing to help herself, so here I am trying to help her myself. I hope this clears the air."
There has been much speculation about an affair between Gosselin of the reality show "Jon & Kate Plus 8" and third grade school teacher Deanna Hummel -- and now Usmagazine.com reports the tryst has been confirmed by a family member.
Gosselin shot back at the allegations in an interview with Kate by his side today.
"It's really upsetting," he told Entertainment Weekly. "I may be guilty of choosing the wrong time and place to hang out with my friends, but I am not guilty of cheating on my wife."
"Our main focus is on our family and working through this," wife Kate said.
But the mistress' brother claims ever since Jon, 32, met Deanna, 23, in January at a Chill Lounge in Reading, Pa., and the pair sent each other $3 shots, the father of eight has been in relentless pursuit of the teacher.
They were subsequently spotted soaking up the rays on the his front lawn seven days after the pair was photographed at Legends Lounge at 2 a.m. -- with Jon not wearing his wedding ring.
Deanna has denied the affair and said the two are just buds.
"We're just friends," she told People. "It's absurd that anyone would think otherwise."
"He's a very nice guy, don't get me wrong. But he's married with eight children. ... has a great family life. I would never ever think to pursue anything."
But Deanna's brother claimed to two got down and dirty and that she and Jon would "pretty much stay locked away like two teenagers. It was weird. He's a grown man."
"A lot of the time, it was pretty, um, gross listening to her, you know, um -- how do I say this? The walls are thin. Let's just say that. I mean, no one wants to hear his sister having sex, let alone with a married dude who's, like, almost twice her age and who has eight kids and a maybe-crazy wife. Ick. Nast," he told Us.
