Kate Plus 8 star Kate Gosselin sat down with Good Morning America on Monday and talked about the fifth season of her show, and also addressed issues with her 12-year-old son Collin, who apparently accused his mother of abuse while enrolled in a home for children with educational and behavioral challenges.

The reality star said it's difficult for the 12-year-old to be away from home, but she’s “definitely” in contact with him. When asked if it was a hard decision for her to make to send her son away, she said, “It was not even really a choice. It was on the advice of his doctors and it had to happen."

When asked how her son was doing, the blonde said, "He’s plodding along and we are too. It definitely was necessary. I’ll go to the ends of the earth for the best for each one of them. This is the best thing I can do for him right now, so that comforts me.”

In the pre-taped interview, Amy Robach brought up the recent article in Life & Style about abuse claims. In the sit down, Amy said, "There are reports that Colin told staffers at his treatment facility that he was abused by you, and child services opened an investigation."

Kate did not confirm nor deny that a formal investigation was under way, but said this is par for the course for the controversial family. "I'm in the public eye. I have been investigated many times ... It's always unfounded, obviously."

"So they're all unfounded?" Amy asked.

"Yes," Kate said. "Absolutely."

The 41-year-old currently has primary custody of her kids, 16-year-old twins Mady and Cara, and 12-year-old sextuplets Leah, Hannah, Alexis, Joel, Aaden and Collin. Her ex, Jon Gosselin, only has partial custody.

Last week, in an interview with Entertainment Tonight, Jon claimed Kate refused to tell him where his son was. The father said, "I have an idea where he is but I don't really know where he is," he said. He added that his ex only told him that Collin,"was in a special school for special needs kids with behavioral problems."

Seems like the whole family's got problems!
