Jon Gosselin had to pull the plug on his Harrah's Resort appearance in Atlantic City, N.J., this Sunday, but Life & Style can exclusively report that he's being replaced by super-hot Ryan Kwanten, who plays Jason Stackhouse on HBO's vampire show True Blood.

"TLC forced Jon to cancel," an insider tells Life & Style, referring to the channel that airs Jon & Kate Plus 8. But he's not alone. "Kate Gosselin was scheduled to appear at the Resorts casino in Atlantic City on Sept. 4. However, TLC forced her to cancel the appearance," adds a second insider."
