She says that in her home state of Louisiana, where she lives, this is a common thing to do.

Clarkson is from Fort Worth, Texas. She has two kids, River Rose, 5, and Remy, 3, as well as two stepchildren from her first marriage to Brandon Blackstock. When asked how she disciplined her children, she said, “I’m not above a spanking,” which some people don’t like. And she doesn’t mean a hard beating, just a swat on the behind
She then explains why she acts the way she does by saying that her parents spanked her and she did well in life, so she is happy with herself. She went on to say that before she does anything, she always gets a warning.
The Voice coach went on to say that she is from the South, where spanking is common.
