Kate Gosselin’s brother and sister-in-law, Kevin and Jodi Kreider, are opening up about the stars of TLC’s Jon & Kate Plus 8, slipping the beans on an alleged agreement between the two that stipulates that family patriarch Jon Gosselin is permitted to see other women while they were filming their TLC show.

The couple claims that Kate told Jon they could lead separate lives so long as they continued filming the show.

“All we know is what Jon told us, that Kate came to him with a contract saying he could have girlfriends and that he can do his own thing,” the Kreiders spill in a chat with RadarOnline this week.

“In exchange Jon needs to show up for filming,” Kevin told Radar. “But otherwise he has the freedom, certain days, to do whatever he wants.”

This is a trainwreck for all to see,” Jodi remarked sadly.
