Kevin Kreider, the brother of Kate Gosselin, is sounding off about the wildly-publicized, televised split between Kate and her estranged husband Jon Gosselin -- and both he and his wife are urging viewers not to watch their hit reality show.

In a new interview with RadarOnline.com, Kevin and his wife Jodi say they are "angry" that the split was used as a ratings booster for their TLC reality series, "Jon & Kate Plus 8." They say they worry about how the publicized split will affect the couple's eight children.

"We're just so heartbroken and sad about the announcement that can be so life-shattering to a young child," Kevin tells the Web site. "And, it was used as a tease, it was used to gain ratings without any regard for my nieces and nephews…."

Kevin tells Radar that he is outraged that the "detrimental" breakup was televised, and asked viewers, "Please stop watching."

His wife Jodi went on to say: "It was the saddest thing to witness. This is family. We lived a life with Jon and Kate for years and we've developed really close relationships with each of the kids, and to know that this is being viewed by millions and used as a ratings booster. It's horrible. It's horrible."
