With their marriage apparently on the rocks, Jon and Kate Gosselin mark their tenth wedding anniversary Friday.
And while, we knew Kate was tough.. yikes!
A new video -- posted on YouTube Thursday -- shows just how strict she can be.
In the video, Kate sits with her 8 kids prior to them doing a television interview.
"I want a drink!" Mady yells. "I haven't had a drink all day."
Kate says nothing.
Mady says: "Mom , I'm going to get dehydrated!"
Kate responds: "Yes, me too."
Kate then orders a bottle of water. She takes a drink, but gives Mady nothing.
"I need a drink now!" Mady begs.
Kate scolds her to "be quiet." Mady then cries: "You're really, really mean!"
Jon and Kate Plus 8 airs Mondays on TLC.
