Jon and Kate (Major)
The other "Kate" in Jon Gosselin's life has called out the reality dad's alleged two-timing ways in a new interview. Kate Major told E! News on Monday that Gosselin needs to "man up and tell the truth" about their relationship, which she says was on its way to being serious before he left her in the dust for his ex, Haily Glassman.

Gosselin was also slated to chat with E! the same day, but canceled at the last minute. RadarOnline.com has learned that his employer, 'JK+8' network TLC, stepped in to kill his appearance. Apparently, they never appproved it.

Major, 26, said the 'Jon & Kate Plus 8' star urged her to quit her job at Star magazine so they could be together without any conflict of interest and that he promised to break up with Glassman, 22, on a trip to New England. "I know the truth. He knows the truth. Unfortunately, she did not."
