Reality TV dad Jon Gosselin spent his wife's birthday with another woman halfway across the country, according to a report.
"I went out to Utah for, like, five days," Jon said. "I just wanted to get back out there and ride with my friends. It just happened to fall on Kate's birthday."
The "Jon & Kate Plus 8" star ditched wife Kate on her 34th birthday and spent time with gal pal Deanna Hummel, 23, at a Spring Gruv party at The Canyon in Utah that happened to fall on March 28 -- Kate's birthday, Usmagazine.com reported.
Kate celebrated her birthday at home in Pennsylvania and took the brood to Charm City Cakes where she ate a slice of lemon birthday cake, a trip shown in the most recent "Jon & Kate Plus 8" episode that aired Monday night.
Jon was first linked to the young school teacher he was reportedly spotted with in Utah when the pair met at the Chill Lounge in Reading, Pa., in January and began downing $3 shots together. Jon has been pursuing Hummel ever since, according to reports.
The married father and the alleged other woman have denied the tryst -- but Hummel's brother confirmed last month that the two were more than just friends.
"A lot of 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," her brother told Usmagazine in early May.
Kate has spent the last week with the kids at a retreat on Bald Head Island, N.C., while Jon was photographed sipping suds with some lady friends in upstate New York.
Rumors of infidelity by both Jon and Kate has fueled speculation that there is trouble in their marriage and created a growing rift between the two.
